A gathering of employees inside the walk-in refrigerator (hence the need for a sweater) of a restaurant for the purpose of becoming inebriated.
"Every customer was a dick today! Now that we're closed, we should have a sweater party before we start cleaning."

A gay party where the dudes arrive wearing only sweaters. The lack of clothing makes for easy action.
I just got back from my second sweater party in two nights and boy does my ass hurt. Luckily I get to lay around the house and watch football all day!
