Boweller 

Boweller is derived from the term disembowel & describes a girl so ugly that her looks could practically rip out your guts. The expression originated in Ireland, most likely in North Dublin street slang.

We were cruising for chicks in the club but got there late so all the hotties were engaged leaving only the bowellers

Bowellergic Reaction 

An upset stomach from bad food or irritable bowels syndrome. See Delhi belly.

I shouldn't have eaten the leftover food from Delhi Spice Explosion. I'm having a bowellergic reaction and may need to be in the bathroom for the next hour… or two.
