permission to blow tubes 

Nautical. Requesting permission to blow hot steam on the tubes in a naval superheated boiler. Often thought to refer to a sailor by the name of Tubes, but this is not correct. The permission is needed because there will be a release of some smoke when tubes are blown.

Engineering Officer: Request permission to blow tubes, sir.
Officer of the Deck: Permission granted.

Isn't worth the powder to blow 'em up 

The kind of person or group of persons who are actually worse than worthless. So much so, that as you contemplate canceling their ticket, you are forever mindful of how expensive a pain in your ass they have already made themselves. Oh to be sure, they gotta go, but as cheaply as is humanly possible so you can recoup at least some of the loses they have cost your ass.

Ya know somethin' Phily? There aren't enough aspirins in the entire aspirin taking planet to make the headaches go away like this mamaluke's been makin' for me... an' yet, he isn't worth the powder to blow 'em up. I want him gone-all-day-long, like yesterday. Understand? ...but we gadda make this on the cheap as much as is freakin' humanly possible. Do I make myself clear? Marone!This chiseling wastling degenerate cock sucking madda fuck! Oh, he's gone. Right the fack now.

Money to blow 

It's a game. After oral sex, when a guy blows a load on the girl's face and then throws a wad of cash on her face. Whatever sticks, she can keep.

Person 1: That chick you were with last week was on a serious shopping spree.

Person 2: Yea, she won a ton of money when we played "money to blow"

came to blows 

Rather than alluding to a physical altercation, this much-more-benign past event was merely where a dude ejaculated from being sucked off.

I really liked da hot chick who attended da neighborhood barbecue, and so I asked her if she'd give me some head. She agreed, but since she'd arrived with another fellow, I avoided any potential unpleasantness by asking him if he was okay with dat. He gave his consent, and so da only thing dat "came to blows" was my cock inside said cutie's mouth.

To blow a 3-1 lead 

When you are so close to win but then you lose

"I don't want you to blow a 3-1 lead"
"I made a mess and blew a 3-1 lead"
"I wouldn't have blown a 3-1 lead if I kept up with the effort"
