Can people actually choke/trap someone with legs?

So i was dating this girl a couple months back who had pretty strong legs and she tried choking me with them but i found it pretty easy to get out but dont know if she was just going easy on me

Is someone actually able to choke someone with just legs no triangle? Or even just hold them so they can't get out? I saw a couple videos but could tell i was a skit
