Thunder Grundle

During a fart, when air is compressed between the grundle and a hard surface- the air erupts to the nearest exit, usually out the front of the crotch. It is thunderous, not just for the thunderous noise it makes, but also because of the unsettling direction of the blow.

I had a serious thunder grundle in math class, i think i sprained my taint.

thunder thighs

a girl with perfect hips and thighs and knows how to rock a bikini. Usually has the best body out and goes perfect with abs. Thigh gaps arent even needed if you have thunder thighs, your basically perfect already! be careful not to judge people by this, and dont use it against them.

thunder thighs are the opposite to fat so dont make it out to be

person 1: dayumm girl you got some thunder thighs!

person 2: biggest hottie out
