funkyboy
Someone who acts like they're living the party life in high school while being an adult. This includes still living with your parents despite having a good paying job, dating girls much younger than them albeit at age of consent yet under the drinking age, doing drugs, regularly posting in their snapchat story of them smoking weed or doing drugs or partying, and near-constant shitposting.
If you keep doing that funkyboy ass shit, you're gonna always be a funkyboy and the world is running out of room for funkyboys.
