“Sip” and “sip on”, what’s the difference?

The direct object of 'sip' is the liquid itself. To use this example, you can sip coke. To describe the thing the liquid is in, you would need a proposition. 'On' works, as in, 'sipping on a can of coke'. 'From' is another way to say it: 'take a sip from a can'.

The number of people not getting this joke is alarming. The photo says “siT on”. Not sip on. Intimating an act of very personal nature.

Oh boy… It’s a joke reply, and kind of a crude one heh.

Sip - usually a single instance. Sip on - a repeated action. To get a bit more advanced, it's a question of grammatical aspect. Semelfactive - an event that usually occurs at a single insurance: sneezing, blinking, and in this case, a single sip. Frequentative- actions that occur repeatedly over a period of time.  To bring attention to the difference: "I sipped on my Coke during the meeting." - throughout the course of the meeting, I was taking periodic sips of the Coke. Doesn't really matter when or how often, just note that it was a repeated action. "I sipped my Coke during the meeting." - during the meeting, at some point or another, I took a single sip of my Coke. Now, not every speaker is going to strictly adhere to these guidelines. This is just how I and others may interpret these rules.

I see some people saying “sip on” means it’s more of a continuous action, but if I say I’m “sipping a coke,” it’s still a continuous action. I don’t think that’s necessarily a meaningful or accurate distinction — “sip on” is just slang(ish).

But it says "sit" not "sip" so I have no idea what you mean, "to sip" would be to take a small sip of something and "to sip on" a drink would probably be closer to nursing it which might or could imply that it's smaller than a regular sip.

"Sip on" implies gently and slowly drinking something over an extended period of time, by sipping in longer intervals. "Sip" just refers to, well, the simple act of sipping.

People are going into the subtleties of the difference between "sip" and "sip on" but really the main reason it says "sip on" here is just so it matches "sit on". You can "sip" or "sip on" a Coke and either one will sound fine and be pretty much interchangeable, but if you want to say that you're putting a can of Coke up your butt, "sit a can" doesn't work.

OP, in case it isn't obvious, this is a dirty joke. They are suggesting that the shape of the tall can is to "sit on" which is slang for using it as a sex toy. You would normally say you sip "from" a can. The "on" was used to make the joke work.

Sip is for drinks themselves (beer, soda) where sip on is for containers (bottle, can)

Ohh

"Sip on" is when you do it continuously. Like for example Jake has been sipping on the cola for the last five minutes. Correct me if I'm wrong.

Normally I'd just say "sip", never "sip on". In this case they're adding the "on" so it matches "sit on". It means the same, but a bit more poetic.

I just wish I had her sweet sweet s s sweet can.

Many people have noted that "sip on" carries more of a connotation of sipping repeatedly. This is true, but it would have been fine to omit it or replace with "sip from" for this joke--nothing here depends on the sipping being repeated. In this joke, they're specifically using "sip on" as an echo of "sit on"--this kind of parallel structure is often used to increase the impact of a statement.

Can I have a sip? She sipped her tea in front of the fire. I’m going to sit here and sip on my margarita. “Sip on” is less formal.

"sip" is more in-line with how modern english verbs are used "sip on" is still widely utilized, and has largely the same meaning "sup upon" is the old fashioned way to say it, and illuminates the evolutionary pathway the phrase took

"Sip on" usually means doing the action of "sip" over time (in a continuous manner).

Why did he sit on a high can 🤣

2 liter

I'm sure that to rhythm with "sit on" is part of the reason why "sip on" is here

It sounds like artistic licence to me - sip has “on” added on to make it seem like it’s a direct replacement for “sit on”.
