Mostly Irish expression for: "stop being an idiot" or "act more maturely"... literally: "act more wisely". Typically said in a scolding manner.
1. "god you look soooooo hot in that tight top..." "Hey you know I have a boyfriend, wise up."

2. "Stop acting like such a clown, it's a sophisticated party and they aren't impressed so wise up."

Get the wise up mug.
When someone believes you originated from Texas or other southern state when you lived in Washington for a while and are English.
Howdy! Didn't you come from the south of the US?

No, I lived in Washington for a while and I'm English! That's a bit of a Washington wayward wise up!
