Not exactly I think. "Craquer pour" does mean to fall for. It can be either a person or an object. For example: "J'ai craqué pour ce manteau" : implies you bought the coat. "Faire craquer un homme" : to have a man to fall in love with you. This usage is informal but not rude and it's perfectly ok to use it any situation. There's another usage though that's quite rude, I think. I'll give you an example. "T'as craqué ou quoi ??" : means something like "what the hell went through your head??". But again this is fairly rude you should only use it to people you're close to but even then, it sounds quite aggressive. Hope this helps

Bonjour On a craqué tous les deux → We both fly off the handle. On a craqué l’un pour l’autre → We fell in love. Cela dépend du contexte : Craquer →to go mad. Craquer → to be enthousiastic. Both senses of the word are colloquial language..

Bonjour Milly! Quel est le contexte?
