Ri: 1. A way to holla or holla back at somebody
2. To announce you've just done something awesome
3. To agree with somebody in a quick flashy way
When said multiple times in stages of three plus "Ri Ri Ri" this shows more value than simply saying "Ri".
Use at own will, but please use correctly and on topics that are worthy of this awesome term.
2. Ex: "I'm hella crunk, Ri Ri Ri".
3. Ex: "Yeah I love that band, don't you AP?" "Ri" says AP2
