Grundy Thundy

When you bang a fat chick and your scrotom slaps against her thighs with a furious bang.

n. 2. A pair of grandma underwear

The Grundie Gang is an electronic commune of like minded people who promote self love. The members of the Grundie Gang are known as "Grundies." Their logo is a pair of cotton "grandma" underwear because Grundies believe comfort is fashion and natural (non-synthetic) materials matter.

The Grundies started as American Twitch streamer, and musician, ReinaMystique's community name. Grundies enjoy good music, food, art, and culture.

The Grundies have a Discord and use the hashtag #grundiegang on all social media platforms.

I love hanging with the Grundies. They always have positive vibes.

Man one: How was your tinder date?
Man two: Great! She ended up face down ass up so I planted a foot and gave her a Rumple Grundy.
