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 a blowjob 

when your girl is giving you a blow job & her dad calls to say he's on his way before she's done.

In extreme cases, you may have to hide your erection to go meet her parents.

Warning: This may result in blue balls if you don't finish off yourself. Try to avoid repeated incidents.

guy 1: dude, did she swallow?

guy 2: nah, her dad called before I was finished. I only got half a blowjob
