When someone cool sponsors party favors to a number of other cool people and even mizes, usually by buying a keg of beer or passing around endless bong hits.
When Bob hangs out there's always flowage and he scores the fine green, we should get him a bong for his birthday next week.
Someone who is a ninja and has the ability to rap on a level that can't not be matched by any other style. Even some of the most renowned rappers that have existed, currently active, and those who will emerge in the future will not be able to compete with someone who has the title of Flowkage.
Whoa!!! He can really spit those lyrics. He must be the Flowkage of the Hidden Spit Village.
