basically dumb shit,often pedophilic or toxic. Bad friend vibes
"Dude this girl is so hot and she is almost my age,16!"
"Dude you are 22, do not pull an Ewan."
When "pulling a Ewan" you fumble the bag; not being able to be with someone you like; making the other person lose interest in you
Josh: Hey Greg, I think this girl that really liked me is losing interest in me.
Greg: Aw man, don't be pulling a Ewan, that's the worse.
Fumbling the back with every single girl that shows interest in you
Dude I feel like I’m pulling a ewan right now, I’m terrible at talking to Emily
