Feeling you get the morning after throwing up/ falling over/ talking to the wall about the universe being made out of segments on account on having over-indulged in the drug ketamine.
I thought I threw up on my front doorstep last night, but when I came round I realised it was my flatmate's bed. Major regretamine.

like forgetamine, another word for Ketamine, the drug. A strong narcotic, ketamine use can develop slight feelings of paranoia or a sense of regret.
I wish I hadnt done so much regretamine last summer I keep forgetting stuff.
