Spit the Dummy 

Australian Term: To indulge in a sudden display of anger or frustration; to lose one’s temper. The phrase is usually used of an adult, and the implication is that the outburst is childish, like a baby spitting out its dummy in a tantrum and refusing to be pacified. (Dummy is a pacifier)

'There's no reason for me to spit the dummy,' he said. 'Why do I have to be a rude cunt out of the car when I've demonstrated what I can do inside of it?'

The dummy end 

The end of the measuring tape that starts at zero. All an individual has to do is hold the "dummy end", while the other person stretches out the measuring tape and does the actual measuring. Commonly used to describe a complete moron that is incompetent at a given task.

Roger: Uhh Scott I noticed you ate your steak with a knife and spoon earlier, so why don't you hold the dummy end of the measuring tape and I'll measure.
Scott: Cool..!

Justin: Man, did you see Mr. MacCormack the other day shoveling his driveway!? He was using a fuckin' icepick!
Tristan: Haha yeah, he definitely holds the dummy end

The Dumbo

When a guy is getting a blow job and is at the point of climax; he grabs the girl's ears and shoots a load down her throat.

My bitch got out of control last night, so when she was blowing me, I gave her the Dumbo! Suck on that peanut bitch!
