French slang title I’m hooked

What does it mean, genuinely?

Oh I was actually mistaken I thought it was a play on words for the slang for man “le mec” so “la mec” using feminine pronoun la is a cool choice ig

but I can’t read cuz la méche is just a lock of hair. Sorry to disappoint my dude

or a wick

I think it means “a secret” in slang i took French for like a year so sorry if I’m wrong

No, it doesn't mean a secret. It's either a lock of hair, but that's quite unlikely given the context, or a wick like for a candle

Ohhh okay thanks
