To fail a drug test or piss test. Drug tests are usually given by either a probation officer or a parent/guardian. The test requires for you to urinate in some sort of container, while afterwards your urine is tested for illegal substances. If you test positive for any illegal substances, you just dropped dirty.
Dude, my PO is comin' tomorrow. I'm gonna drop dirty for sure.

Serial position in which a penis-haver lies recumbent and holds his erect membrum virilis pointing upwards. The partner, having eaten a vindaloo the precious night, squats about the erect "gherkin" and drops the drty bomb.
Oh my goodness, a roffer is about to drop a dirty bomb on the gherkin!!
