look up any word, like the eiffel tower:
A grannon is a seemingly nice guy who cheats you out of your money and has sex with gay guys behind your back. He steals from you even though he seems like an amazing guy. He can bullshit his way out of anything.
OMG my bowl got stolen. That guy I thought was nice definitely just pulled a grannon.
