So the punchline is… Pull out your dick and piss in her mouth because…

She’s a public bathroom?
I don’t think I get horny post comics.

I chuckled a little.

I took it as her being aggressively kinky and provocative to tease and embarrass her uptight partner, nothing says one way or the other as to if she’s really into that sort of thing or just messing with him since he clearly wouldn’t go through with it, and the punchline being his flustered and mortified reaction rather than just the sexual innuendo.

But the artist wasn’t shy about playing up the horniness and titillation either.

However, that’s not the only way to look at it, and it’s not like we’re dealing with Shakespeare here.

You’re wrong, this is obviously a reference to Shakespeare’s Taming of the Shrew. In act 2, Scene 1 Petruchio says to Katherine: “Who knows where a wasp does wear his sting - In his tail.” After a back and forth Petruchio says: “What, with my tongue in your tail! Nay, come again, Good Kate, I am a gentleman.” This comic clearly swaps the roles of Petruchio and Katherine to say something very profound about our society, definitely not a dumb horny comic
