They got to be beaming that pipe you know what I'm saying
Yo them Megas got 'em going up to see Captain Kirk

from Public Enemy – Don't Believe the Hype Lyrics on Rap Genius

Meaning

Flavor Flav accuses mainstream media of being on crack (hypocritically as it turns out).

The phrase Beam me up, Scotty from Star Trek somehow became associated with taking crack in 80’s Hip Hop terminology. Whenever you hear rappers talking about beaming up or Scotty, they’re usually talking about crack.

PE also referred to crack hits as megablasts (megas) in their song of the same name.
