<Noun> A wretched state of mind stoners encounter when too high and their remote to the TV won't work; usually stuck on the worst infomercial ever made. These fools are too lazy to get up to change the channel and are thus, in a torturous place because they are forced to watch bad television.
Jay accidentally stepped on the remote so he and Miller were stuck watching Oxy Clean infomercials all night long. They were condemned to weed purgatory.
<Verb> The act of blowing a joke or a rip, usually by sputtering out sentence fragments or by stuttering. This usually leads to laughter by one's friends and extreme embarrassment to the person who 'derailed.' The offender will stay very quiet for a long period of time following one of these outbursts.
