Grump dumpling

Someone who never has anything nice to say, ever. There's always a rude comment coming out of their mouth.

Person 1: Becca was so rude today. She pretty much told me I suck at my job.

Person 2: Don't pay any attention to her. She's just a grump dumpling.

Grumpy Burt

A form of being Hangry, a complete disdain for food that doesn't turn up on time.

"I know your breakfast was late, but don't be a Grumpy Burt"

Grump Lump

When you’re grumpy AF and just want to mope.

Dude: “I don’t wanna go. I’m cranky.”

Chick: “Wow, you’re being a Grump Lump.”

Grumpy Plunge

Unclogging the toilet with your grandma's dildo.

Grandma! The toilet is clogged again and I can't seem to find the dildo. I wish you'd buy a normal plunger because I'm sick of "grumpy plunge".

Niagara Grumper

An explosive shit. Comes pouring out of your ass with seemingly no end to the flow. Like a hot waterfall of shit.

I ate some bad oysters last night and today I experienced the worst Niagara Grumper. I couldn’t get off the shitter.

Grampster

A man or woman aged 65 years or older who considers them-self to be a gangster. They are usually thugged out with ghetto wear, and have tattoos all over their bodies.

Did you see that 70 year old Grampster with the flat billed Twins hat? I bet that old bastard is hard as hell and is packin' serious heat.

Guy 1: You better watch out for that Grampster, he won't hesitate to bust a fat cap in your ass.

Guy 2: Yeah but he'll probably break a hip trying to catch me!

I bet sawdust and mothballs would fly out of his pockets if that old ass Grampster fell over!
