To upchuck a small amount of cum, into your beard, immediately after swallowing a load.
I had way too much mac n' cheese for dinner, so when I was having anonymous sex in the park afterward I got all gaggy and Jizzy Jasoned.

I wonder if that Jizzy Jason I pulled last night has anything to do with my recent acid reflux.
