HOOAAAAAAAAGH!
Meaning, have sex with me. Can be said casually as a joke most people will take lightly. Try saying it to someone of your sexual preference in a desperate tone of voice and see what happens!
"Hey, do me!"
"*pats legs* Oh, ha, you're so funny!"
to shag someone. sex can be hard to say if u dont really know the person, so you just say something like "wanna do me babe?" instead of "wanna fuck me babe?"
In Halo or similar FPS's where the co-op mode allows unlimited respawn, collection from your own corps, and full life respawn, it's an aloud request you make to your partner when you're really low on health so that you regain all you're health, you can pick up all of your ammo, weapons, and items so that you're ready for battle again with full health
