A tealer is a way of referring to a guy who's a raper, player, or try-hard. The perfect word for a guy who just won't get it through his head that he's not getting with you tonight! (etymology:a chain email)
Omg! That guy is such a tealer, he won't give up and it's really annoying...
A man who is obsessed with tea, he is usually fragile, weak and arrogant of the world around him. In most cases British.
Look at Tealer drinking his tea he has no idea he's being robbed.
