Drop a bomb from five foot up 

In act in which one stands upon the toilet seat and proceeds to release a giant turd into the toilet. Amateurs make a large splash. Professionals make no splash. For some, this is better than sex.

"Dude! last night I want to drop a bomb from five foot up and it made no splash, but Granny was over."

Drop a dirty bomb on the gherkin 

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!!
