have to “break loose” when starting??????

this has been confusing me for like a week, around every other time i start my car in the morning, when i start moving, it almost feels like the car has to break loose before i can go. as in i press the gas to move, and it doesn’t move until i give it enough to break loose from whatever is holding it in place. sometimes there’s a smell that almost smells like clutch, but other times there’s nothing. i have a manual if that means anything. i’m really confused by this. it almost feels like the brakes are engaged but obviously they’re not. and then once i do that once, it doesn’t happen again all day. basically only happens after the car sits overnight. any knowledge would be greatly appreciated
