A neurotransmitter believed to regulate mood. SSRI's inhibit the reuptake of serotonin in the brain (leading there to be more serotonin left as a result), hopefully improving the mood.

Personally, a good blast on the Codeine cheers me up more than any SSRI.
Perhaps it's my endorphine system rather than my serotoninergic system that is fucked.
A lack of Serotonin is believed to be a cause of depression. It also controls appetite, among other things.

Antidepressants often (through various mechanisms) increase the amount of serotonin in the brain.

MDMA (Ecstacy) causes a massive (cascading) release of serotonin in the brain - responsible for both it's euphoric effects, and the depressive aftereffects (less serotonin remains in the brain, until generated again)

A neurotransmitter that is most known for regulating mood.

While the release of serotonin has been commonly associated with producing feelings of happiness and content, it is a misconception that this is its primary function (it's not). Serotonin's range of functions in the human body are very broad and complex. The chemical plays a crucial role in cognition, memory, reward, and learning as well as numerous physiological processes such as vomiting and the constriction of blood vessels. Without Serotonin, you probably would not even be alive.
Person 1: This video gives me so much serotonin.
Person 2: Same! I can feel the good vibes flow through me.
Me: I hate to be a party pooper, but FYI Serotonin isn't entirely responsible for giving you "the good vibes". What you are describing is a complex rush of hormones and neurotransmitters made up of serotonin as well as dopamine, oxytocin, and other endorphins. These are commonly referred to as your "happy hormones".

serotonin bomb 

When on the drug MDMA (Ecstasy) as serotonin trickles down your spinal cord someone stands behind the intoxicated and push all their muscles on their back upwards and into their head as the person receiving the serotonin bomb hyperventilates, they then rub their shoulders and have the person stand up extremely fast causing a burst of renewed serotonin.
I was getting into a bad roll and K gave me a serotonin bomb, I was better in seconds.

serotonin police 

someone or something that shows up when you're happy and sucks all your joy away.
we were having fun until the serotonin police popped up.

Word of the Day on October 28, 2026
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
You didn't get any napkins with your takeout pork fried rice? Womp womp.

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
