Shallow abbreviation of first name "Tom" or "Thomas". Comic shortening of an already short first name. "T" as in "Mr. T". This, among other now imperceptible ponderings, through transmogrification, equals the capitol "T" mixed with the logical addition of "Bag"; especially when under the influence of tequila, hence, T Bag.
"Don't come running to me for answers as to why we destroyed Mrs. Wilson's tulip garden with the delivery truck....Blame it on Mr. T Bag".
