When you try to talk to someone and the other person is frequently about to to head out or about to do something else and appears to be avoiding the conversation; this person is pulling a keith.
You: Hey, what's up man? Want to catch up on things real quick
Friend: Hey man, sorry I'm about to head in the shower then to the gym tonight.
You: Oh okay man...you don't even have like two minutes?
Friend: Not really, I was just about to get off the computer
A few moments later...
Other friend: Hey, so is Joey around to chat?
You: No, he is pulling a keith again.
Other friend: Sigh..again?
