The act of being caught red handed, especially for something sexually explicit. Derived from Chris Hansen of Dateline NBC's "How to Catch a Preadator." See dead to rights.

When somebody says/does something so unbelievably dumb that they need to just sit down, shut up, and not do anything else; when the stupid is so strong that just one seat will not do. Also can be used as an expression of self-disapproval when one has an unbelievably dumb thought.
1) Donald Trump: "I will build a giant wall that Mexico will pay for!"
Smart person: "Have several seats."

2) My boyfriend and I were talking about our futures, and he said he wants to do some things before graduating college but one depends on our relationship. After a few days at home on break, I'm starting to think he was talking about marrying me. We're both 16 and haven't even kissed yet. I need to have several seats.

The command used by Chris Hansen, of Dateline NBC, before publicly humiliating and destroying would be child molestors on national television. No matter how much the child molestor wants to run, for reasons unknown to man, he cannot leave and always takes a seat.
Chris Hansen: Why don't you have a seat?
Child Molestor: Oh shit! I swear I wasn't going to do anything with that 13 year old boy. I have to go now!
Chris Hansen: Why don't you have a seat right over there.
Child Molestor can't help himself, and has a seat.
