Blow your back out 

To fuck someone so good, they can't walk for a couple of days. Hence their back is blown out.

Boy: Damn, girl, I can blow your back out
Girl: Um, I don't think so, I have a soccer game in the morning and I'd actually like to walk.

Blow job 

Something stupid high and even middle school girls will do in an attempt to be popular or to get a boyfriend. Never works, all it ever accomplishes is to get the stupid girl labeled a ho or slut and possibly get her a case of herpes.

Dude, Hannah is so desperate to be popular and liked that she has absolutely no self respect and will give a blow job to anyone.

Blow Job 

When wearing something similar to a poncho, break wind and trap it inside, creating a dutch-oven. Then after every thing is up to par, open one sleeve and blow the noxious air into a bystandards sniffer and enjoy the reaction.

CAUTION: Be careful not to release ovens contents onto yourself!

Person 1: "Dude? What stinks?"
Person 2: "Man that guy wearing a poncho just gave you a BLOW JOB!"

Blow Job 

The giving or receiving of a large hit of meth from a long "V" shaped tube. The "giver" starts by taking a big hit which he in turn blows through the tube all the while keeping the fire on the meth and blowing more meth into the "receivers" waiting mouth, until they can take no more. May cause you to drop to a knee. Keep in mind that should one fall after receiving a Blow Job, the five second rule does apply. After numerous hits from the Blow Job tube it then becomes a Jo Blob

I stopped by for a Blow Job before work and will have no problem working my double shift now.
