When you are banging a 1-legged chick from behind...and after you bust....u kick out that one leg out...and she falls...then you jump around yelling "kickstand kickstand".
I was at a War Amp meeting and hooked up with this hot 1-legged counselor....i bent her over and gave her a kickstand.
An unattractive individual (guy or girl) who always is accompanied by better looking individuals. Meaning they are the "kickstand" that holds up the prize.
