Spewnami 

An ever increasing radius of nausea caused by a violent gastric eruption.

Particularly dangerous as each subsequent event could set off yet another spewnami.

Whilst coming in to land, the child got so upset it threw up, causing a spewnami to ripple and ricochet through the cabin.

Spewtamize 

The act of regurgitating the contents of one's stomach onto the anus and/or anal rim of another as lubrification before performing sodomy (fudge packing).

1. "Pierre's ass felt sore after Sunny spewtamized in it"
2. Marguerite was jealous while watching two hunks spewtamizing in each other.
3. Sunny and Pierre feel hungry after spewtamizing lovingly in each other (co-spewtamization).
