Giving someone a hug which almost literally squeezes the breath out of them.
Okay... you can hug me, just don't give me a hug overdose!
Hugging someone so hard that they can't breathe. Can be harmful to people with asthma, or if administered by fat people.
Alright, you can hug me, just don't give me a hug overdose! Last time, I couldn't breathe!
