so wait the saying "get that head get that bread and leave" refers to getting stimulation to the male reproductive organ using the oral cavity usually to reach climax most refer to as "cumming" and then proceed to collect "bread" or the currency used in that place in the world that usually holds value in the stuff you are able to acquire with it, and then proceed to leave the (usually other sex) partner for an undisclosed reason.
making sense the right way and getting smart and creative along the way.
Bread= load a lot of knowledge and understanding
Head= Using your mind to see things around you. You perverts.
I don't care how boring the teacher may be but as long as he is making bread, getting head along the way it is ok with me.
