Da Flounda
Da Flounda is a highly advanced dating technique in which you place your hand in between the legs of a girl or guy (depending on what floats your boat) and smack the inside of their thighs back and forth. This recreates the effect of a flat, two sided, bottom feeding fish being trapped inside their legs. When the person looks at you in astonishment at what you're doing you simply yell out "DA FLOUNDA!!" as an explaination. Making-out then ensues.
I went out with Twanda last night and the bitch was ice cold. She wasn't feeling my game at all until I pulled out da flounda, then it was slow head all night long.
