panty-banging 

When one masturbates by rubbing his penis with a woman's pair of underwear.

Aldo was super horny so he stole a pair of Helena's underwear and was panty-banging them all night long.

Party Banging 

A method used by a "nice guy" using a party setting to get drunk and get in some girls who in the morning will think you did it because you felt pressured due to the party setting and the booze, thus your "nice guy" rep remains intact.

An effective technique to maintain your "nice guy" status while tearing through a crazy boy-band amount of ass without being labelled a "player".

Does not work for girls, that is still slutty.

Mike didnt want to ruin his nice guy image so he did some party banging last weekend with a couple girls and his rep is intact.

Banging pants 

Pants worn during or before the act of sexual intercourse that help facilitate intercourse. Generally they are pants that are easily pulled down or removed for purposes of sex. The pants can include a lube reservoir as well as a condom dispenser.

A girl wanted a quickie last night. Good thing I was wearing my banging pants so I was ready to go.
