It’s an acronym standing for Can’t Remember A Fucking Thing. It’s usually used to describe embarrassment at being unable to remember someone (CRAFT moment); going onstage as the lead in the latest theatrical performance and your mind goes completely blank (CRAFT situation); the next morning after a night when you got pissed as a fart and woke up in bed cuddling a traffic cone and a string of fairy lights wound round your prick.

Periscoping is an advanced, but non-sexual form of spooning. Unlike being the big spoon or the inverse, little spoon/backpack/jetpack, both partners share equal responsibility.

At the same time, the second partner 'shades their eyes from the sun,' and shouts, "Land ho!"

The act of whipping the dicc out while fully erect and placing it carefully between the gut and the elastic of your underwear/assorted leg covering.

The concealing of an erect penis by folding it behind your waist band, leaving the head of your penis exposed underneath your shirt.

The act of giving a blowjob to a man standing up while giving handjobs to 2 men facing the guy in the middle.
