Apparently, you can end or punctuate any conversation with the question/invitation: Suck my dick?
Example:
Me: Hey, how are you doing there? Suck my dick?
---
Me: Looks like rain...
Bitch: Yep.
Me: Suck my dick?
---
Slut-Ho Whore-Priestess: You just stepped on my foot!
Me: Suck my dick?
And if you're lucky, they really will suck your dick.
