If your friend tells you that the speech you just made was really verbal, he means you used too many words, overstated the point, went on too long, were redundant.
Verbal simply means, "having to do with words." If you hit someone that's a physically assault, but if you say nasty things to him, it's a verbal assault. Sometimes we use verbal to mean "spoken instead of written," usually to talk about agreements we've made. A child who is verbal is a child who can speak, and we call someone who's very articulate a verbal person.
