Indicates for how many successive days you can live on
pasta (
plain or with something) without turning grumpy. Especially important when you are a poor student. If you are beyond your pasta tolerance treshold (PTT) you might want to
switch to rice, polenta, potatoes etc. for a few days until you reach, for example, your rice tolerance treshold (RTT).
"Ey dude,
pasta for dinner tonight?"
"No man, I'm really beyond my
Pasta Tolerance Treshold. I'm going for rice instead."
"Alright, I see what you
mean. Your PTT is not to be messed with!"
