"M" is for Men.

Situation; Me, Jolene and Becca went down to the gym to buy shorts.

Raymond: Uncle, can I have MEN'S shorts?
Bewildered Uncle: What?
Raymond: MEN'S SHORTS.
Bewildered Uncle: Orh! What size?
Raymond: Size M.
Bewildered Uncle: Okie.
Raymond: "M" for "MEN".

Becca's at the background giving me the weirdest look ever, and Jo remains unaccounted for.

Raymond Angelo- 100% MEN.
