To be Kev'ed

To be Kev'ed means you really ate too much and you feel like dying. You abolutely need to fart unless your stomach is going to explode

I've been to Laurens's pansion and we had a huge raclette. Ho God I was so Kev'ed...
I asked everyone to cover their ears so that I could fart confortably.
Then Pascal heard it, laughed so much that we had a fart contest
as a conclusion, that's funny to be kev'ed, it all depends who you are with
