Mushroomed up 

To get all high and mighty on mushrooms. This is a state of being evinced by happiness, hallucinations, mightyness, and the epitome of awesome. This isn't a state to be undervalued. Envy those mushroomed up.

Dude: I'm going to get all mushroomed up and find god.
Other dude: That, good sir, is an aspiration of manly proportion.
Dude: That's the only way I do.

Mushroom Syndrome 

(n) - A syndrome where you're fed bullshit and kept in the dark. Derives from the method of cultivating mushrooms: they add a lot of fertiliser and keep them in the dark and damp.

A person can suffer from Mushroom Syndrome in any way; the only circumstances are:

(1) A person doesn't tell you everything about a certain situation concerning you/and or them

and;

(2) They tell lies.

Sarah: So how's your relationship with Andy going?

Bree: OMG! He gave me Mushroom Syndrome! It turns out he was actually gay, which he never told me about.

Sarah: Wow! So what did he bullshit to you about? You know, the other half of the Mushroom Syndrome?

Bree: Oh, he told me he didn't break the blender but it *actually* was him!

Growing mushrooms 

Used mostly in anime and manga, the term growing mushrooms refers to when a character has become immensely depressed or saddened. The character is often shown to literally grow mushrooms on their body, signifying that their soul is, for the time being, in a dark and dank place. (Mostly occurs with more dramatic and over the top characters who can't stop crying every 2 seconds 😒)

Senpai: (crying because the girl of his dreams thinks he's dramatic and egocentric)
Girl: "Senpai, quit growing mushrooms around me; the smell is absolutely noxious!"
