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.
To vomit violently, creating a "tidal wave of spew".
I drank so much last night, I was caught in a spewnami this morning.

Profuse incident of vomiting, a portmanteau of "spew" and "tsunami".
Marie got very drunk and soaked Reg with spewnami.
