"THUNDER THIGHS" are a fat girls thighs that are so humoungous, big & fat that they clap together when they walk. This produces a loud noise which goes like "SLAP, SLAP, SLAP" , hence the "thunder" part of the word.Also causes earthquakes,volcanic eruptions,and tsunamis from just one clap.So make sure you stay away.People have been know to wander near the thighs and never seen or heard of again.EVER

when someone has extreeemely large thighs (guy or girl) may be a very muscly guy and may involve OVERHANG. these thighs are so powerful that when running is done by the individual, the ground may rmble like thunder hence 'thunder' and some times sparks may be produced like lightining.

A - "oh wait no its only Jimmy and Singo, jesus look at those thunder thighs!!!!!"
