periscoping
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.  This aids in either concealing the tiny/enormous size of the male anatomy.  Males usually partake in this action while either being embarassed by their size or if they for example are asked to come to the front of the classroom for a presentation "at the wrong time".
Ah shit son mah dicc is soo rock hard right now and Mrs. Cocklesuck just called me up to the front of the class to present for show-and-tell. I guess Ill just tuck it like a periscope...also known as periscoping.
