Most often a white man with a very large penis ranging from 6.5 - 8.5 inches. While the individual may or may not realize it he is such a stud that women and a few men find him to be irresistible and would do thing for and with him they normally wouldn't do. While a Thomas may be a nice guy on the outside they are a freakin' stud in bed and drive women wild.
When I walked in on Thomas in the bathroom I never knew a white boy could be so huge!

When a cock is so big it could have it's own face. Similar to the train featured in Thomas the Tank Engine.
