Bang Day is the day that you first have sex with the partner of your new relationship. Bang Day does not refer to one-night stands - it is relationship dependent. If your relationship lasts longer than one year, Bang Day then becomes known as your Bangiversary - the anniversary of the day you first had sex with your partner.
"Hey man, how long you been seeing Sarah?"
"Two months - yesterday was our Bang Day."
"Nice, congratulations dude."

Originated in Brixton (London). A type of group sex activity developed by contorsionists in the early part of the 21st Century.
A box is placed in the center of a ring of people, where a contorsionist climbs in and is then penetrated through various well placed holes in the sides of the box.
Box banging is not gender, or sexual orientation specific.

After wanting to bone Sally for so long, she really disappointed me last night in bed and it was a bang wreck!

Loud attempts, often futile, of asserting one's dominant role or position within a particular sphere. Believing or suggesting, without merit, that you are the most important, powerful, or influential individual within a group.
Everyone knows my boss is a worthless asshole, so his constant dick-banging in meetings just feel sad.
