Instead of taking a dump on someone's saran-wrapped face, a warm carl involves taking a dump on someone's face FIRST and THEN wrapping it up with saran wrap. Some people prefer to shit into the saran wrap instead of on his/her face. Either way results in a layer of poo followed by a layer of saran wrap, hence "reverse".
