Much like smoking or drinking someone up, "blowing up" in this context refers to giving someone free coke.
Person 1: "I wanted to leave for that party, but Andrew just wanted to keep doing lines at his apartment."
Person 2: "Did he at least blow you up?"
Person 1: "Yeah, I got a bunch of free blow-ups. Did you make that up just now? It's pretty good."

When someone blows you up it means they let many others know about something you're doing, or what you have that you don't want others to know. A place can get blown up as well, for example if you know a chill spot where a selected few come to hangout, it could get blown up if a lot of people find out that it's cop free and chill.
