Slang (with other meaning):
The act of playing with any stick-like object by oneself in a bedroom or a small tent, in which the activity may be over an extended period of time and sometimes repeated.

My brother pitched a tent in my living room and called it Jack n' Tony's Shack. He played some serious hockey that night, and ended up pitching 5 field goals in his own net and wouldn't pass the puck until we were out of fresh towels.
