Chicago White Sock

A good luck pre-game ritual for Chicago White Sox fans where your girlfriend slips on a black sock (normally used for feet) on your cock and jacks you off until you cum into the sock while you sit back, relax, and strap it down with a beer, preferably a Miller lite (or modelo if your girl is Latina)

This is similar to the Clark Street Cock Sock, which is performed exclusively among men within the gay community and into a blue sock before Cubs games instead.

My girl surprised me with the ole Chicago White Sock before the game that was so good I nutted through the sock and Giolito threw a no-hitter!
