A term of farewell, whether it be for the day or state of mind, referring to the switching from side A to Side B on a vinyl record player (also known as the flipside).
"I'm outta here. See you muthafuckas on the flipside."
"Here's a ten strip of acid, I'll see you on the flipside."
The equivalent to butterflies in the stomach scenario, but much more accurate. It literally doesn't feel like a pounding heart, but more like the heart is doing gymnastics at high speed.
Flipping occurs in situations such as:
-thinking about/being with someone you like
-infatuation
-nervousness
-fear -emotion overload
-being scared
This is also used as a noun ie. heart flippage
"Yeah, when I was with him, I just had these heart flips."
"I didn't even think it would but there was just this random heart flippage, and suddenly yeah, I liked her."
"She says she loves him because she always has heart flips, but I think it's just infatuation there."
