A sphincter is a circular muscle that normally maintains constriction of a natural body passage or orifice and which relaxes as required by normal physiological functioning. The rectum is the concluding part of the large intestine that terminates in the anus. The average length of the human rectum may range between 10 and 15 cm. Its diameter can be compared to that of the sigmoid colon (the part of the large intestine nearest the rectum) at its onset. Combine these and you get Rincter.
...and so the sabretooth tiger was stabbed in the RINCTER by the woolly mammoth.

Ricter Scale 

The scale of the intensity of the need to expel a "running-induced crap." 1 would be slight abdominal pain; 10 would be an explosion capable of setting the sky on fire.
"I was so humiliated when I hit a 10 on the Ricter scale at the last mile of my long run. At my running buddies bought me beers afterward to make their making fun of me bearable."

Hey, guys, I think we're going to need to have a ringtervention with Steve. His "Wake Me Up Before You Go-Go" ringtone is really starting to drive the chicks away.
