shooting blanks into a dead end 

When both partners of a relationship have been fixed and can't get pregnant. The male has had a vasectomy and the female her tubes tied or a hysterectomy. The male therefore does not have sperm in his ejaculate and the female no way to deliver an egg to be impregnated.

Female 1: "The sex with Joe was great last night. I love not using a condom."
Female 2: "Hey aren't you guys afraid you'll get pregnant?"
Female1: "We're both fixed. He's shooting blanks into a dead end!"

Going Down a Dead End 

When someone is hitting on someone not interested in their gender.

Hey Greg, you know that girl Sarah that you were hitting on…well don’t go down that street…she’s pretty lesbo…trust me you’re going down a dead end.

A dead end feature

When a movie ends with a goal never being achieved. Or it’s not known if a goal was ever achieved.

That movie was such a dead end feature. I can’t believe I even watched that.

deadend friend

A friend that over the years you have become attached to for unknown reasons. It is usually someone you have invested a lot of time and money in, all in good fun, for a while. They always let you down but you can't seem to stop hanging with them or helping them. They are typically low lifers who take what they can get from anyone and leave everyone thinking they're a good friend, until they're gone.

"i thought debbie was gonna be there for me, turns out she's just my deadend friend."
"why bother go pick debbie up for the party? she's just a deadend friend."
