When you want to simultaneously tell a
friend to go fuck themselves and imply vulgar homosexuality (without directly calling somebody gay because that's outdated now), you tell them to go fuck a poo, dude. It's insulting because the implications are that they have direct access to a dirty
ass they can go and fuck whenever they please, and if not, they'
ll have to find one. It suggests a homeless, unwashed, backed up
ass that has enough shit it it to the point where you can fornicate with it. But either way, they'
re better off fucking a poo than hanging around you.
"Go fuck a poo, it's all you'
re good for anyways!"
"Don't call me. Don't come by my house. We're
done. And go fuck a poo."
"Oh
please. Fuck a poo and then ask me that again."
