drug knock

When a strange man knocks on your apartment window at night. You don't know him, so you're hoping he just wants to sell you drugs.

"Oh my gosh did you hear that? Some creeper just knocked on our window!"

"Don't worry - it was probably just a drug knock."

Knock First

An emo/pop punk band located in the San Fernando Valley (Southern California). The name derives from when a teenager (most likely male) is masturbating and gets walked in on to be caught in the act; hence knock first.
Changed their name to Down For The Count in 2003 due to a conflict with the name of an ABC show also called "Knock First".

Drummer: Man this fucking sucks, we came up with the name first.

Lead Guitar: Yea, what a gyp.
