bottom feeding grub

Typically a commonly named grub called the LankWayne or RancidLuci from the lowest of the low class of grubs. They're hairy and disgusting. They eat all the putrid shit found in the gutter from which it lives and spend their sorry existence telling these made up trash stories.

Did you hear about that/those bottom feeding grub now?!

I'm so glad I'm not a bottom feeding grub! I like showers and accurate info!
