bum bum war 

when walking down the street and a random person violently thrusts their bum into you and then continues on their walk as if nothing ever happened. This ends up inferiorating the victim and continues the bum cycle.

{girl walking down hallway}

{guy eying her hungrily}

{guy thrusts bum into girl and then sandwiches her into the locker jostling her a little bit}

{guy walks away as if nothing has happened}

The girl has just been victimized by the violent bum bum. and she continues to victimize others with this vicious cycle known as the bum bum war.

Awkward Bum Warmth 

(noun.) The awkward feeling, sitting on the toilet for a dump and realising that the seat is warm, because somebody has recently taken a dump there, finding it repulsive but strangely comfortable at the same time.

I just went in the toilet to swirl one out and experienced Chris' awkward bum warmth.

Bum Warmer

A steel barrel with combustible material inside. Usually lit during cold winters by bums in urban areas to keep warm. You can see these Bum Warmers in alleyways, under bridges, and on sidewalks. Usually the said barrel is surrounded by several bums and homeless trying to stave off the cold.

Bum1: Begging for change is sure hard work. Lets go find something to keep us warm

Bum2: I know of a good alleyway with a nice cozy Bum Warmer
