Only Cans

Alright listen up, smarty pants. So, OnlyFans is a site where people post content, usually NSFW. This joke is like, "what if there was an OnlyFans, but instead of that, you watched this person smack baby daddies with Twisted Tea?" Then the comedian makes a pun by saying "Only Cans", implying canned beverages like the one used for smacking. I bet you need a drink with your IQ.
