underhopped 

is the condition that results from taking an unbalanced diet in which certain nutrients are lacking. Specific for this condition is the lack of hops in your daily food intake.
Depending on the amount of hops that is missing in your body this condition may result in normal body balance and muscle coordination, normal speech, normal behaviour and seriousness.

The World Health Organization cites malnutrition as the greatest single threat to the world's public health. Improving nutrition is widely regarded as the most effective form of aid.

The opposite is overhopped.

I feel underhopped. Please hand me a beer!

The party yesterday was dull. I've been severly underhopped.

Undernauseated 

The state of being far below the mental breaking point how many stomach cringes a consciousness can endure before all weakness, disguised as pain has completely evacuated that body.

The undernauseated talent enjoyed victory.

Undernose 

The act of placing a COVID mask under one's nose to facilitate easier breathing by completely defeating the purpose of wearing it at all.

Example: "I told this lady at work to put a mask on but she undernosed it so I walked away."
