A bernie - A slang word for cocaine. People use it to know if they can

A slang word for cocaine. People use it to know if they can expect a big party or a lot of money.

They said there was a bernie at the party, so I brought my whole class.

I got a bernie from my friend, and it made me feel like I could run a marathon.

My mom said I could have a bernie if I cleaned my room. I did it in 2 minutes.
