When you have had too much to drink and you bang on the wrong person's door.

A spin-off of "Party Knocking" made famous by LMFAO..."Sorry for Party Rocking"
"Hey guy in apartment #3, sorry for party knocking last night. I had a lot to drink and thought you were someone else's apartment!"

Get the Party Knocking mug.
The act of repeatedly kicking a foreign or locked door very hard until someone answers. Most commonly used where a regular knock will not be heard, such as in the prescence of very loud music.
The neighbours party was bumping, so we had to use a party knock at the front door.
