Ducking

Leaving early or hiding, sometimes in order to avoid a certain person or a group of people.

Ex.#1
"Chris is coming over tonight, he wants to talk to you."

"What? Oh Emm Gee. Fine, I'm ducking. I don't feel like dealing with him tonight. Just...call me when he leaves."

Ex.#2
"I'm gonna go over to Clint's tonight and see a movie with him and Courtney."

"Yeah? I guess I'm ducking out then, I'm gonna take a disco nap, so call me when you guys get out of the movie."
