Rumbleweed 

A "Rumbleweed" is what martial artists, particularly Brazilian Jiu-jitsu practitioners will recognize as a random hairball that goes rolling-by, like a tumbleweed, during training. The "Rumbleweed," is the accumulation of everyone's hair, from grappling "rumbling." And, somehow, it always ends-up in a ball, rolling around the mats.

"I don't think Professor swept the mats. That's the third "Rumbleweed," I've seen today!" "Hey, there goes a "Rumbleweed!"

Ramblin' man 

A man who often has a strong affinity for women but is too much of a restless soul to settle down; therefore, he often breaks hearts. His own as much as the women he is with.

Waylon Jennings - I'm a Ramblin' Man.
You're standin' too close to the flame. Once I mess with your mind, Your little heart won't beat the same. Lord, I'm a ramblin' man, Don't mess around with any ol' ramblin' man.

Led Zeppelin - Ramble On.
Got no time to for spreadin' roots. The time has come to be gone. And tho' our health we drank a thousand times. It's time to Ramble on

Allman Brothers Band - Ramblin' Man
Lord, I was born a ramblin' man. Tryin' to make a livin' and doin' the best I can. And when it's time for leavin'. I hope you'll understand. That I was born a ramblin' man.

Cardinal Rumble 

When two very large people get it on in a very small and warm place causing them to turn red like cardinals.

Hey dude why are you so red?

I was just banging big Bertha in the hallway closet, there's no A/C in there.

Oh I see you two were having a little cardinal rumble!
