Floptimus Prime 

A middle-aged dandy, usually seen propping up bars in South London. Often seen sporting a mix of modern and traditional attire; such as a silk cravat, a velour jacket and brightly coloured slacks acquired from the Kings Road.

Takes chatting up and bedding women equally as seriously as consuming large quantities of alcohol. Thus when both combined, a performance issue can arise(or not), thus one becomes "Floptimus Prime". He must announce his new name.

Picked up a frauline in the boozer last night. I had already sunk 8 liveners. Got back to my digs and it all went south. I AM Floptimus Prime.
