crimping my vibe

To copy someone's vibe, style or other personal "trademarks"

Example 1:

Me: My friend just announced he's getting a guitar right after I showed off the guitar I just bought, AND he got the same guitar strap as me? he's crimping my vibe hard.

Example 2.

Me: Did you see Ethan is using Jay's catch phrase now? He's totally crimping her vibe.
