It happen when putting on a medical exam glove and trapped air makes a qweef like sound,gleef.

Wife: “Have you put the sheets out to dry and put the towels on?”
Husband: “Yes. You know I am a grown adult also used to live alone so you do not need to micro marrige me”

The guy who cut me in line at the taxidermist was a real gleef.

I was watching Rachel getting egged again on Glee and I laughed so hard it caused me to Gleef.
