The most wonderfull sight to be introduced to american men in the last few years. The rise of a womans thong or G-string, while her pants are lowered. T-bird, only works with pretty, sexy woman. When a T-bird is exposed on a fat woman - it is then called a 'T-bomb'.
Hey bro', Is that Carl's sister over there bending over? Yeah, check out her T-Bird. Nice !!!
