Hella cred
When you do or say something cool that people recognize someone for or just something a lot of people lied that someone did. Cred it short for Credit as in getting credit for something you did. Hella means you got lots of it.
I got hella cred for delivering a pizza to an elementary school. I was hearing pizza chants on the way in & giving high fives on the way out. I felt like the f***ing man!
