Half Blow Job
when someone gives you a blow job but instead of the entire penis going into thier partners mouth its done from the side...sort of like licking an envelope.
The only thing Mike can get is a half blow job becuase hes girlfriend doesnt like the entire thing in her mouth.

Half Job
A half of a hand job. Usually happens when the girl realizes half way through that she doesn't want anything to do with your disgusting penis, so she goes home instead. Often the male at the wrong end of this technique will come up with excuses in order for his friends to not look down on him, such as "when you have a chick squeezing on your dick it's not pleasurable."
A painful, unsatisfying and never endinghand job. This is due to the fact the the girl administering it has no idea what she is doing and it always ends in you saying stop or her giving up.
