Slang: Tommy boy?

[kelley]

<forwarded query from another list>

I've got a student using the nickname Tommy Boy on the discussion board, 
and I have a vague memory that it's British slang for something this nice 
cleancut young Christian virgin doesn't want to be known as.  Anybody remember?

Thanks.
