look up any word, like donkey punch:
 
1.
22 skidoo and 23 skidoo can be used interchangably. The phrase originated in New York City. It was the result of policemen having to disperse groups of pervey men who would hang out near the 23rd street subway stop to watch womens skirts get blown up by air coming up from the subway airshaft through the sidewalk. 23rd street is the flatiron district and was known for a high concentration of women office workers.
I think that guy over there is a cop, we better stop insert illegal activity and 22 skidoo.
