It's Always Sunny in Philadelphia2005

Frank Reynolds:
You don't look like a gay guy.

Dennis Reynolds:
That's because he's a bear.

Mac:
What?

Dennis Reynolds:
He's a bear. You see, some gay guys are twinks and other are bears. This gay guy's a bear. By the way, we are totally cool with that. To each his own.

Frank Reynolds:
Wait, I'm a little confused here. What's a twink?

Dennis Reynolds:
A twink is small and slender, like mac.

Mac:
Oh, no, I'm too muscular. I would be a bear.

Dennis Reynolds:
Uh, don't think so, bro. Not hairy enough.

Frank Reynolds:
Smooth. Now, I would be a bear.

Dennis Reynolds:
No, no. See, I don't think you'd be a bear either. As a matter of fact, I don't know what you'd be. You're definitely not a twink.

Frank Reynolds:
I'd be a top, that's for sure.

Mac:
Can a twink be a top or is that reserved for bears?

Dennis Reynolds:
I'm sure there's a great deal of switching back and forth but I think more often then not bears are tops, unless they happen to be power bottoms.

Frank Reynolds:
What's a power bottom?

Mac:
A power bottom is a bottom that is capable of receiving an enormous amount of power.

Dennis Reynolds:
Actually Mac, you've got it backwards. You see, the power bottom is actually generating the power by doing most of the work.

Frank Reynolds:
Does power have to do with size or strength of the bottom?

Mac:
Now Dennis, I heard speed has something to do with it.

Dennis Reynolds:
Speed has everything to do with it! You see, the speed of the bottom informs the top how much pressure he's supposed to apply. Speed's the name of the game.
