Senay Line 

The middle of a grading spectrum. For example, in most American schools, a 100 point grading system is used. Therefore 50 would be the "Senay Line". This term comes to us by the educational philosopher Mike Senay who reminds us that "50 is half of 100".

"Son, your 53 in English is simply unacceptable."

"Father, I have passed the Senay line and thusly proved my capability in this field you call 'English' "

San Andreas Fault Line 

The San Andreas Fault Line is a sexual maneuver where a male spreads his partner's buttcheeks and proceeds to defecate in his partner's spread buttcrack. Once he has finished, he then presses his partners's buttcheeks together. He then proceeds to shake his partner's butt in any way he can, which can include but is not limited to shaking or slapping. While he is doing this, he is screaming "EARTHQUAKE". After he is finished, he calculates how much feces escaped the buttcrack during the earthquake and gives it a rating on the Richter Scale.

"When my girlfriend said we should go to California to see the San Andreas Fault Line, I didn't expect an earthquake THAT big."
