The feeling you get when you mix booze and drugs/medication, can also be defined as being Cross faded. The difference being, MUHH is more of a sick feeling than a heavy intoxication.

Term founded on the night of 9/15/2018, when the MUHH'd person attempted to describe how they felt--like a "spaghetti noodle"--after ingesting anti-inflammatory medication with alcohol earlier in the day.
Dave: Yooo I was so MUHH last night that I cuddled with the toilet and fell asleep in the bath.
Joe: Y'all need Anti-MUHH.
Dave: Anti-MUHH?
Joe: Water. Lots of it.

Get the MUHH mug.
A noise you make when you're nutting
"Hey, how was last night with Karen?"
"Oh, it was great and I nutted and screamed out muhh!"
