Nackname
A short, smelly version of a name that comes from the end of someone's name, like a f***in' stink bomb.
My name is Matthew, so my nickname is 'Th' because I'm a f***in' smelly stink bomb.
Her name is Samantha, so her nickname is 'Tha' because she smells like a f***in' old sock.
His name is Alexander, so his nickname is 'Er' because he's a smelly, f***in' back-end loser.
