When you cum into someone's mouth and they spit it back into their hand and throw it at you.
That bitch hit me with a gob grenade!
A lemon hand grenade is a lemon, which someone cuts the top off of, hollows out, and then ejaculates into, and then re-seals. After the re-sealing of the cum filled lemon, you shove it halfway in a woman's vagina or asshole, and then punch the rest in, resulting in the lemon exploding inside of the woman.
"I just emptied half my fruit bowl trying to give my girl a Lemon Hand Grenade!"

STUN GRENADEEEE

Another word for "flashbang" in some games.
"Watch out, Jon has a stun grenade!"
When fisting your partner, using a tightly balled up fist fully insde them, without warning, you yell BANG!! while simultaneously opening your fist, fully extending your fingers, creating the sensation (and possibly similar physical affect) of a grenade going off inside them.
Warning: a poor manicure may enhance the hamburger effect.
