Acid on acid

Acid-on-acid reptilian effect or simply "acid on acid", happens when you squeeze a fresh piece of lemon into your mouth at the pick of your LSD trip in order to achieve a sudden reptilian state of consciousness sending you back to the Jurassic period for a short time.

Acid is a ridiculously powerful drug. It's measured in micrograms (that's 10 to the negative 6, kids). A few hundred micrograms is enough for a fairly decent trip that'll last between 8-12 hours.
Guaranteed to blow your freakin' mind. I strongly suggest listening to the Grateful Dead while under the influence. It is not advisable to drive or operate heavy machinery while tripping. Going to work or attending class while zonked out of your gourd is also discouraged; the fact that your pupils will swallow your entire eye is a dead give away that you're on something.

A substance often found on sugar cubes or tiny pieces of paper. Less commonly found on sour patch kids, or starburst. When taken orally, effects are generally produced within 60 minutes and can last up to 14 hours. A wonderful experience, but fucking brutal on the body and mind for days afterwords. If dosing hard, expect after effects for up to 7 days, and expect your back and neck to feel like fucking shit for a while also. A serious drug not to be taken lightheartedly. Acid will take you deep to the core of it. yeah. Don't listen to the fucking hippies who are like "dude i like tripped out so hard and watched this building breathe dude, I love acid" those people don't even know what the fuck they are doing to themselves. Its more like "wow I am so lucky to even be drinking this fucking glass of water, acid made me realize how small and insignificant I am to the cosmos, but yet made me appreciate love and life so much more, I'm going to call my mom and tell her I love her right now...' Can be a painful, awkward, and brutal experience, Usually tho it is worth it.

Something that's very cool, interesting, or surprising. Can be used in place of epic.

Something that is original, very cool, and off this wave. Takes the place of the overused word dope (dope is for idiot school boys who put subwoofers in their mom's mini van). It is the opposite of basic. It's way cooler to be an acidic bitch than a basic bitch, period.

When a woman unexpectedly inserts a finger two knuckles deep into a man's ass during foreplay.
