look up any word, like ebola-head:
The delightful, and often dangerous, event when a young adult combines LSD, commonly known as Acid, with sexual activity of any kind, most commonly, good ol' fashioned sex. This applies especially when the hip youngster is losing his virginity or doing any kind of sexual activity for the first time.
"Ask me what I'm doing this weekend."
"I'm Jamie-Flipping."
"What's that?"
"Acid and Sex."
"No way."
"Could almost Meaty."
