A nickname to suggest one (a
male) is very into having sexuall thoughts about other men. Can also be used to say that a certain
male has a fetish for one particular name, and will tend to have sex with
people with this name.
You think one has gay thoughts about men, you then
call them "Tomo".
If one tends to spade and have sex with
girls only the same name. For example '
Hannah', then you call them "Tomo".
