20-minute lull 

The phase in any conversation, usually occurring every 20 minutes or so, where the conversation gets quiet and no one really knows what to say. This is the point in the conversation where everyone involved will be desperately fishing for topics and might take up talking about the weather.

"So.... how about that... err... I don't know what to say."
"Me either... we must've hit the 20-minute lull."

20 Minute Snooze 

A young, attractive male has been partying like a mother fucker for the past 2 weeks. The only time he takes off for partying is to go out for a nice big dinner. Then he proceeds to tell everyone that he has gotten only 20 minutes of sleep the past week and he needs his rest. The group then calls his ass out on it and calls him a bull-shitter. Shortly after this, he will end up clubbing for the 15th straight night.

Dis: Yo man I doubt I'm going out tonight
Nasir: Why man it's friday?
Dis: I know man it's a great night for clubbin but I only experiences the 20 minute snooze last night.
Nasir: O dude that blows, u must have had a crazy night of clubbin
