After feeling sorry for those freshmen girls who tried to score the hot seniors, I examined only the hottest ones & said to myself: "I'd fuck Meg Griffin".
A covert way of saying "I'd tap that ass" or "I'd hit that" were the "couch" equates to the the woman you you want to have sex with or the vagina you want to explore. Derived from Dave Chapelles "Chapelle Show" from his Charlie Murphy / Rick James skit.
