Spending your lunch break on the toilet jerking it

Tim was no where to be seen at lunch, he was probably having a lunch rush

lunch rush minute 

The modicum of time--approx. 60 seconds (depending on the capacity of the lunchroom)--one must rush into the lunch line before it starts looking like the line to the bathroom after lunch.

Charles: Hey, Jim, you being chased?
Jim: Not now, Chuck, it's the lunch rush minute! Gotta get to the line before the juniors cut in front!
Charles: Don't bother, it's just turkey sloppy joes. And it seems to be coming out the same way it came in.

japanese lunch time rush 

The most famous line of the character from Kuroko's Basketball, Kagami Taiga. It's when people in japan tend to all rush and flock in a food establishment (in the anime's case, the school cafeteria) because the japanese only have a 30 minute lunch break. That sucks.

"Woah! Look at all those Japanese people going crazy for that special sandwich. THIS IS JAPANESE LUNCH TIME RUSH!"
