An amount of time longer than a second and a lot longer than a sec, but shorter than a hot second and a lot shorter than a minute. I'd say it's usually about 3 and 1/2 seconds.
David Hasselhoff: "What up dogg, that's a pimped-out Magic Johnson throwback you've got on. Let's go smoke this joint."
Gary Coleman: "Wait a hot sec. I have to feed my dog...dogg"
Mary-Kate: "So how was R. Kelly last night? I hear he's a one minute man."
Ashley: "Not even. More like a hot sec man."
Ricky: "So Tom how did you do in the race yesterday?"
Tom: "I came in hot sec place."
Ricky: "You know what they say...hot sec place is...well...probably about the 1 and 1/3 th loser. Loser."
Tom: "Shut up Ricky."
A brief moment, comparable to the length of a second.
Hank: Dude, how long were you at her crib?
Ben: Just a hot sec. ;)
