There's lots of interesting somewhat unique words or phrases that you can search for here to bring up funny memories and threads. The key is something fairly unique and not overused where you get 15 pages of results
Three of my favorites are: Arsed, GERD and Milk Truck.
I was shocked to see nine pages of results for arsed, including (both could and couldn't be varieties), but only one page for "milk truck".
What's your favorite unique term? (trike and stew not allowed)
