A landmine consists of placing a roach (or clip) into a bowl. Then, placing weed and/or tobacco on top. Such that the bomb, very much like a normal time bomb, is placed under a layer of dirt or grass. Proceed to smoke the bowl back and when the bomb is hit the smoker who tripped it must yell landmine.

A landmine is similar to a "grenade" in meaning, as it refers to a SKINNY, ugly chick. This term was believed to be first said on the famous MTV reality show, "Jersey Shore" when Mike "The Situation" referred to a girl his friend bought home as a "landmine".

Usually refers to a huge bitch with no neck. She's so fat that her body meets her chin which leaves no room for her neck. These types of HUGE bitches can be found within a group of hot chicks ready to Cockblock anytime anywhere. Be aware of Landmines, they're extremely dangerous.

ps. When Landmines turn around, head turn = body turning as well due to lack of neck.
