the state a guy gets when sexually aroused; penis fills with blood and stands straight up and often makes a bulge through pants; boxers, etc. especially embarrasing for teenage boys who are turned on frequently and can't seem to control their boners

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.

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.
