When one becomes instantly high after inhaling a large amount of marijuana smoke.

Instantly Baked... "Instabaked!"

Get the Instabaked mug.
1. When one inhales a large amount of hash and marijuana, upon the exhale of smoke, one may or may not be insta-baked - the instant sensation of being "baked" has completely entered your body and you are lifted and shifted, higher than the ceiling.
