The lesser version of smashing.
To smush someone is everything but sex.
Guy 1: "Hey you know Alex?"
Guy 2: "Yeah dude she is hot."
Guy 1: "Well she came over my house last night and we totally smushed."
Guy 2: "No way dude! You rock."
When you hug someone so tight that you start
to mash into one person.
He hugged her so tight, she said they'll smush into one person!
A cushion that one has had sex on.
I wouldn't sleep there! That's Chads smush cushion!
