O que significa a expressão "get one's claws into someone"?

On the previous post, I talked about a very famous expression with the word claw which was "one's claws are showing". If you don't know what that means yet and would like to check that out, click here. This time, we have a second expression with the same word. Those expressions are all too interesting to be left out. Somehow, they're more related to women than men cause if you think well, they're the ones who have long well-kept nails, something closer to what we call claws. So let's get into it.

Imagine you have a friend who's head over heals in love with a guy that's actually already taken. You tell her she shouldn't be flirting with a guy that has a girlfriend and encourage her to look for someone else. Your advice however falls on deaf ears. A few weeks later you find out she has managed a way to make him break up with his girlfriend and finally get her claws into him. When a you get your claws into someone, you manage a way to start a relationship with them, maybe in a not very honest way. That happens when a girl does anything to get a guy she likes. So maybe she lies, manipulates, turns friends against each other, all because she wants to control the boy of her dreams, gets something from him. Sometimes it's not that she likes him to that point, she just wants to get revenge, boost her ego, anything like that. That's it for now. Take care!
