Thumb up your ass

(adj.) Not doing what you should be doing, be it at work or in free time. Pls note it can be 'thumb up my/your/his/hers/possessive pronoun's ass" as needed. I just put "your" in the entry title because it's the most common.

ass-thumbing

Ass-thumbing is when you go to the bar and drink Captain and ginger, and then you strategically place your yourself between 2 people and nonchalantly stick your thumb in someone's butt. The goal is not to get caught and to make the person getting ass-thumbed think it was someone else. Ass-thumbing also goes by " doing the Crosby" Ass- thumbing is believed to be a German tradition, and in the States, there is an ass-thumbing group in the mid coast Maine area.
