Jellatio 

The act of slurping a Jello shot out of it's cup. This can be deemed difficult and time intensive if the cup is particular stiff and/or deep.

"These jello shots are great, but I had to perform jellatio on the cup for 20 minutes before I could get the whole shot!"

The process from which jello goes from liquid to firm.

We have to wait for our jello to jellatize.
