Get the Stiffymug. by xxdecayingashes December 26, 2004
Get the stiffymug. A slang word for erection or hard-on. As an erection is the 'stiffing' of the penis, a 'stiffy' is an understandable slang word. Normally used by children first discovering sexual things.

Get the stiffymug. The most awesome nickname ever. This person is probably the coolest person walking on earth.
And most most certain; drop dead gorgeous, since he/she is compared with a boner.
