When an unemployed stoner scores a bag of weed for you and then takes a portion out for himself before delivering the bag. This serves as a) compensation for the person's time and effort and as b) a reason for said unemployed stoner to find the motivation to drive across town and score a bag - sometimes even in perilous and hazardous driving conditions.
Ah, man, my bag's a gram short! Damn, I guess I got hit with the 'Robin Tax' again! Oh well, at least he didn't charge me for gas!

The portion of a child's meal, Halloween candy, video game time, etc. that a father rightly takes as his own, mostly because you wouldn't be there without him. This particularly applies to things that your father buys for you - because there's no such thing as a free lunch, and life is hard, so you better get used to it.
My kids came home from their Halloween trick-or-treating, and as they sorted through the candy, I took all of their Reese's Peanut Butter cups as daddy tax.
