When a person creates a fantastical lie for selfish reasons in order to make them seem cooler than they actually are, they are in effect "pulling a Rasmus".
Rasmus: "dude, I'm got arrested for possession of speed!"

Dude#1: Wow, Rasmus is talkin some bullshit.

Dude #2: RASMUS, YOU'RE TOTALLY PULLING A RASMUS!!!!
