Theory that states in cases where a woman has small breasts, this is compensated for by her having a nice ass. This theory does not necessarily work in reverse.
A truck with either, extra large wheels, raised body, smoke pipes or a combination of all 3 which are driven by guys (possibly women) who have small dicks. One's need to impress ladies is done with the ridiculous truck size that attracts attention away from the lack of size in other places, or place. Thus compensation trucks are used exactly for, compensating.
Dan: I just bought this new truck, it's raised. Im hoping that girls won't notice my small dick as much anymore now that i gots this HUGE truck!
Joe: Dude, that shit works soo well, my truck gets all the ladies. Im buying smoke stacks, here cumm the ladies ;)

Lady 1: HA HA HA! Look at those stupid compensation trucks...LOSERSSS
Lady 2: We all know what they're compensating for.
Basically a metaphorical liscence given to you when you are completely baked. Usually used when playing games such as pool and you make the stupidest mishits eg: accidently nudging the white (or any ball if you're really fucked).
It's a good liscence that you need for silly fuck-ups whilst stoned.
How do you obtain Stoners Compensation?
Simply say it immediatley after any fuck-up and your friends will agree with you if it actually was due to being stoned and not just pure stupidity.
