That means hello in America.
"In Egypt, that means "hello.""
"What up? That means hello in America."
What Up is a phrase commonly used by Barney Stinson, usually heard at the end of a comically appropriate sexual comment, often accompanied by a high five. Its style varies from time to time as do most of Barney's catchphrases, being either high-pitched or low-pitched, oddly pronounced or even not verbally said.
Open bar for the guys, open casket for the ladies, what up!
Shut the FUCK UP!
What the FUCK…?
Get the FUCK OUT!
OMG! Shut the, What the, Get the!
When you ask someone what they been doing and that kind of stuff
