Verbal Curfew 

When one is unable to talk in ones own house past a certain time (on the phone or otherwise) due to the fact that their parents or guardians are vicious tyrants. Penalties for breaking a verbal curfew include ripping out the tounge, a guilt trip, cutting off the left testicle, and other various punishments.

Friend 1: Hey dude, call me when you get home at around 11 PM.

Friend 2: No way, I have a verbal curfew. My parents will cut off my left testicle if I call you tonight.

Coffee curfew

The time of day at which one knows one can no longer drink coffee (or other caffeinated beverages) without an adverse effect on one's sleep that night.

Five in the afternoon is my coffee curfew. Don't want to be awake until two in the morning. Guess I'll have a beer instead.

"I'm not allowed, I have to be home by 10"

"I'm not allowed, my curfew is 10."

creeping curfew

The insidious, often unauthorized, extension of time restriction placed on nocturnal adolescent activities as further evidence of parental authority erosion and generalized attrition.

Oh, just screw 'em...my parents don't know shit. 11? 11:30? 12? Let the creeping curfew work its magic!

Curfew 

Similar to a booty call, but a more tactful euphemism in a committed relationship. When the maximum allowed time has passed without having sex, either by appointment or by arbitrary desires. Should be looked forward to in a healthy relationship.

1a. "You've been out there all day, it's time to get inside!"
1b. "Sorry guys, I gotta go- it's my curfew."

2. "I better be upstairs and naked by 10 tonight or I'll miss my curfew!"
