Grundy 

A person who is everyone’s gay best friend and known for having the smallest dick in the group. Someone who you can talk to but you just know that whatever you tell them will be bait for them to slag you off with others.

“Oh, I have never had a gay best friend with a smaller dick than me!”
“You haven’t? Just become friends with Grundy”

The act of giving sombody a wedgie after putting sand down their pants or shorts.

The lifeguard gave me a grundy when I bumped into him on accident. I was chaffing for weeks on end, with nothing but pain to look forward to until i went to the doctors for melvin wedgie and grundy reconstructive surgery.

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

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