Straight piping is an aggressive form of deep throat oral sex. This is when a girl lays on her back on a bed (or some other object) and tilts her head back over the edge so her throat is no longer at an angle. In effect, it forms a "straight pipe." Often seen in pornography.

Yo man I banged this girl last night, she was like a pornstar dude! She even let me straight pipe her!

Straight Pipe

Removing a catalytic converter from a car in order to make it sound faster than it is. Can land you with a Section 59 if the police check under the car.

“That car behind me is deafening, is it an AMG?”

“Nah bro, just another idiot who decided to straight pipe his golf.”
