The nectar of the Gods. Smoother than the Mt. Dew, better tasting than Vault. It has just the right amount of caffine, and it will make your penis bigger.
Girlfriend: WOW! Your penis looks bigger!
You: You bet! I've been drinking Mello Yello!

A asian that smokes alot of weed. Therefore does not give a single fuck.

It is recommended that you do not cheat off them on test, because they do not study as much as there hard working counterparts.

Pretty much just an imitation of Mountain Dew *angel chorus*. Most people think it doesnt have any caffiene in it at all, but it does. Yup.

Mello Yello is a drink blessed to us. After the crack of the can, the aromatic citrus fills your nostrils. I swig will send you to flavour heaven, it's orange kick send you into a trance. some people say its a rip-off of mountain dew. But honestly; 99 cents is no turn down for such an amazing drink!
I drank Mello Yello yesterday, and it put me into a trance! THE FLAVOR.
