The phenomena of a man's penis being so aroused that it achieves a glorious state, immeasurable to any other erectile position. The name is derived from the ironic use of words such as "young" and "little" to describe something of the opposite.
I took Sheila out last night, and her huge tits gave me a Youngpeter. She'll never be satisfied by another man again.
