People who are extremely sensitive and tend to be triggered easily, consequently ending in tears.

someone who will cry over the smallest thing out of self pity

Melanie Martinez's debut album that SLAYS AS FUCK

Contrary to the actual words used, a cry baby neither cries nor is an infant, but is a fully grown adult who whines too much and should know better.

A cry baby will normally complain about the most petty things, like there being no packets of brown sugar on their hotel room tea tray, the fact the train is four minutes late, and being dumped by their significant other.

The only acceptable way to deal with a cry baby is to pretend to physically cry when they start complaining, by rubbing ones eyes and quivering ones bottom lip in a totally OTT manner, followed by the put-down "don't cry about it".

Someone who whines and cries.

a person who whines cries and throws a fit over silly bullshit. Someone who whines just to whine and argues just to argue. A silly bitch.

A person who gets easily upset if they don't get thier own way.
