erection

(Slang for hard-on.) 1. A male's most magnificent and majestic display of his virility, when aroused by the sight of a beautiful female or by the thought of sex. 2. The magical transformation of a cock that doubles in size, gets hard as a rock, and stands straight and tall as a soldier at attention. 3. The aroused state of a dick that looks like a huge rocket on a launching pad and feels like a giant stick of dynamite about to explode. 4. Sign to a female who sees or feels it that a male is ready and able to fuck. 5. Opportunity for a guy to show off his magnitude and his potency, when he has one while standing up in front of the class; likely to evoke giggles and blushes from girls, to hide embarrassment at the feelings it arouses.
