The Ernesto is the act of fucking a chick with a condom on, and then at the last minute, right before you come, without warning, pulling the condom off. The goal is to cum all over the girl and make as big a mess as is possible, much to her surprise. It is not an Ernesto unless it is an unwanted surprise for the girl. It makes little sense and is completely inconsiderate, which make the thoughtless act quite entertaining. It is so named after being pioneered by an Italian man named Ernesto.
"dude, I was about to cum and I figured "fuck it, I don't even like this chick", so I had to Ernesto her at the last minute"
A mythical sexually transmitted disease rumored to be in actual existence. It was created cerca 2003 when a manwhore of a student, nicknamed Dejo, from Eastern Oregon University slept with an equally whorish Mongolian exchange student. The two slept with an uncountable, yet enviable, number of other students and it spread like wildfire. No actual medical symptoms exist, however the social consequences are devastating, if not life lasting. The Dejo has been confirmed in at least 7 western states, and is now in Europe and Asia.
"So Jaime banged The Mongol, and then Valerie, who gives it to Landon, who spread it to Singo, and The German Chick too. Which means all of Boise definetly has it and possibly Germany too. Dude, I'm so glad I didn't get The Dejo".
Acceleration marks are crap stains that you intentionally leave in your underwear. They are in essence, the opposite of skid marks, and are so named accordingly.
All that chilli I ate yesterday has let me do some sweet acceleration marks in my shorts. Just a little scratching is all it takes.
