look up any word, like lemonparty:
A joking term referring to the disorientation, forgetfulness, random changes in opinion and taste, and other mental problems that result from chemotherapy. Also spelled chemosabe.
'Why are you dressed up?'
'Because it's Saturday, and we're going to your prat of a brother-in-law's birthday party. Remember?'
'Oh, the Tory Tottenham supporter? I like him. I forgot to buy a present!'
'Yeah...bit of kemosabe brain, there?'
