The act of laying down, looking down at some sort of device on your chest, and scrolling aimlessly through every social media network and letting the time as well as your youth pass on by. This causes not only a double chin but isolation amongst your friends and family.

Slang for two asian boys having a 3some with a hot white horny chick.

Generally, they fit both dicks into her mouth because they are so small.

The "Chins" also masturbate with tweezers.
My boyfriend and his younger brother were double chinning me...when my mom walked in.

Then she joined us.
