Gay T-Rex

Alright, listen up, you big lug. So, you've got "Tyrannosaurus Rex," right? That's a big dinosaur. Now, say it slow: "Ty-ranno-saurus Rex." This joke plays on how that sounds like "tyranno-sore-ass." Get it? "Sore ass" is a crude way to talk about, you know, a butt that's hurting, and if you're talking about a "gay T-Rex," it's implying a sexual activity that might lead to a sore backside. It's a pun, because the sound of the words is similar, but the meaning is completely different and a bit naughty. You probably didn't even notice the wordplay, did you, smoothbrain?
