Heimlich hug 

When someone comes up behind you and gives you a hug around the waist.

Aunt Judy came up behind me when I wasn't looking and gave me a Heimlich hug. She nearly squeezed the life out of me.

Heimlich hug 

When a girl (esp. short) gives you a side hug and her boob thrusts in your stomach.

I love it when my Shawty gives me a Heimlich hug with her fine fun bags, don't care that it makes me wanna puke!
