Named after the assasinated Indian leader, this rather colourful expression refers to the stinging burning sensation one experiences in one's anus when shitting out a curry of the vindaloo or phal variety (i.e. v.hot)
Wow my arsehole is killing me!
Well that's Gandhi's revenge - you shouldn't have had that vindaloo last night.
Noun. A stomach upset, and subsequent diarrhoea
I feel and look like complete and utter shit. Must be Gandhi's revenge.
