Semtex Grenade 

Refers to the result of the process by which a grenade, or ugly friend of a girl you or another wants to hook up with, develops in into a full force semtex grenade,as made popular by the Modern Warfare video game series, after someone agrees to jump on the grenade.

The grenade, mistakenly emboldened by your making "small talk" with her so that your friend can run game on her dime piece friend, begins to think that she is in fact attractive as well. Now in full force, the semtex grenade begins pursuing you, desperately trying to hook up with you.

"Yo, did you hear Mike jumped on that grenade for Tim last night. She's a complete semtex grenade, been blowing up his phone all day."

"Dude, that sucks. I hope he's rocking Flak Jacket Bro."
