Receiving a god tier blowjob to a glorious climax while going 40 over the legal speed limit in a Mustang. The bucking comes in when your leg twitches from great pleasure causing you to slam a pedal down and either break drastically or accelerate to Ricky Bobby levels of speed
Person A: Tammy and I are going to try The Bucking Mustang tonight.
Person B: My cousin tried that once he slammed the brake and flew out the window.
Person A: it's a risk I'm willing to take.

A small green slip of paper with a lucky clover drawn on it left by Leprechauns on St Patricks’ day after they have outwitted the Leprechaun Trap laid out by a child. It is a token of appreciate from the Leprechaun for the child’s hard work, but a reminder that Paddy was not caught.
I found a fresh Paddy’s Luck Buck in my trap but he got away. I know he was here because he used my bathroom and took all my gold. I’ll get him next year!
