After robotripping at Sesame Place, me and Big Bird lit up an afterburner and watched the sunset melt in the sky 8-}-~

Afterburner
1. During sexual intercourse, while assuming the missionary or doggie-style position, the male cums and simultaneously cuts a huge fart while lighting it with a match.
Good for an extra inch or two.
The afterburner, initially man, I'm thinking something to do with cars but I know, I know for a fact this is Urban Dictionary, ladies and gentlemen. It ain't nothing to do with cars.

Afterburner
Marijuana, usually in the form of a joint, that is smoked towards the end of a DXM trip which synergizes with and enhances the remainder of the trip (akin to a jet engine igniting its exhaust fumes mixed with fuel to generate an afterburn)
