A gangsta' nickname that can be used for anybody who is cool enough to bear it. Usually makes more sense if the person's name starts with a T. For example Tiffany.
(v.) T-boning involves introducing the erect penis into a throat using a motion strikingly similar to tea bagging (whence its name). Often times the receiver will be lying on their back, with the head hanging off the edge of a bed or sofa, so as to facilitate access to the depths of their esophagus.
I pwned this noob with easy the other day, but when I came up to t-bone him, rigor mortis had already set in. I just settled for a good ol' tea bagging.
During a threesome consisting of three males of the homosexualorientation, when all three erect penises meet at the same time (usually in a T formation) they all ejaculate on each other for sexual pleasure.
