1.
The spontaneous appropriation of a couch pillow or other domestic furniture product to separate two heterosexual males in situations requiring a state of seatedness, but prone to limited seating space.
I went over to AJ's place last night to watch the game and knock back a few beers, but there was barely any space left on the couch...

Luckily, I was able to grab a pillow off the floor for a manvider to avoid the potentially uncomfortable proximity and awkward arm/leg touching with my buddies.
