Verb - To convince friends to come over to your computer while looking up old classmates on Facebook. Then you leave a grenade. After leaving a "grenade" also known as deadly fart, your friends start throwing up everywhere
I was on Facebook after drinking and smoking looking up Angelo Portale while shitting my pants, I left The Facebook Grenade behind, I called my friends over and when they dashed over, (comma) they inhaled through their nose my noxious gas I left lingering in the air.
