That mustache that boys in middle school try to grow.

Wow, that boy over there has a cool grundy.
Nah man, my sister has a better one.

Grundy

Aimlessly wandering through life as if you have no purpose. Strong lack of focus and attention.

I was going to wake up early and just attack life but instead I just kind of feel grundy instead. I grundied my test today and failed miserably.

Grundy

When you moan about mundane experiences (especially supermarket related) on neighbourhood social media.

My mum loves to Grundy after a trip to the supermarket.

magnum grundy

This is the type of guy who would steal your glass of orange juice. He's just a dick. If you get to know him he can be very nice and will cherish you. The one he chooses to love will get all of his affection, they are pretty lucky to have a magnum grundy.

He's such a magnum grundy, he would be rude to you if he didn't know you.
