Get the stiffy-stuffmug. Excited anticipation of such an immense force that the very thought of it alone could probably cause you to become aroused. Usually used by a female, coming from a male it adds even more to the comedy factor.

Get the Rodeo Stiffymug. An erection. A dick getting hard due to sexual excitement. Hot girls tend to make a guy’s dick all stiffy.
Me: (Watching a Marilyn Monroe documentary film)
My mother: Are you getting all stiffy?
Me: LOL, shut up.
