A sharp lateral flexure of the rectum formed by a transverse fold of the rectum. The chief anatomical purpose is, in homo-anatomy, the grading of penis length.

Jimmy Bean's cock was so huge, it rammed all the way past my third Houston line, rupturing a diverticulum (true acquired) in my sigmoid colon!

Houston, we've had a problem here

Originally a genuine report of a life-threatening fault. Now used humorously to report any kind of problem.

John Swigert, Jr. and James Lovell who, with Fred Haise Jr., made up the crew of the US's Apollo 13 moon flight used (almost) this phrase to report a major technical problem back to their Houston base.

Swigert: 'Okay, Houston, we've had a problem here.'
Duke: 'This is Houston. Say again please.'
Lovell: 'Houston, we've had a problem. We've had a main B bus undervolt.'
