The night after the grenade has been jumped by the unfortunate, it may develop into the semtex grenade (a sticky explosive made notorious by modern warfare 2) where the said grenade will not desist in contacting the grenade jumper via social networking sites or by phone.
The main objective of the semtex grenade is to bombard the grenade jumper with these texts, phonecalls and emails, into furthering the meaningless one night stand towards a more meaningful relationship.
:'Even worse. Turns out she's a semtex grenade, can't get rid of her.'
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.
"Dude, that sucks. I hope he's rocking Flak Jacket Bro."
