mellow-yellow 

1. the putative use of the inside of a banana peel as a halucinagenic drug (a 1960's hoax that became connected with an urban legend about a song of a similar name after the debut of the said song, and susequently spawned more hoaxes, sense 2 is likely also linked to the song)

2. Lysergic acid diethylamide, a hallucinogenic drug

3. a five milligram tablet of valium (from the yellow color of the tablet)

I wouldn't waste my time with mellow-yellow if I were you.

Mellow Yellow 

A joint/blunt rolled with "mello mango" (or any other mango flavored rolling papers), marijuana, any non-pot cannabis related substance, crushed up percocet and the tobbacco inside a Marlboro Smooth menthol cigarette

Hey man, we need to enjoy the scenery more. Let's mellow out. You know man, really get in touch with nature. We need to smoke a Mellow Yellow man. Listening to Led'll do that to you man.
