what the hell is electric charge? Like it doesn’t make sense sense to me how protons are positive and electrons are negative like what does that mean?

those are simply names. we found a force that works between certain types of particles and had to give it a name. what is positive and what is negative are arbitrary naming choices for the two opposing elements this force works on.
+/- work pretty well considering when you bring them together they cancel each other out, so naming them “red and blue” for example wouldn’t be as useful.
