an act of excitement or celebration;
When two men stand face to face, drop their
pants and underwear, put hands on hips and "wag" side to side. This allows their penises to "wag" like a
dogs tail simultaneously. The act
may be escalated by standing close enough for the penises to hit one another to simulate applause.
Tim and John had just beaten
Frank and Joe in the last match of
tennis, and really rubbed it in when they gave a standing ovation via, the double faced
tummy wag.
