When someone makes a reaction that is delayed. Obviously. This happens by means of mental illness or just stupidity.
Dude1: Haha, you suck.
Dude2: (*smacks Dude1*)

((two minutes later))

Dude1: ...hey that hurt!

When you make a kissing sound and motion approximately 15 seconds after your boyfriend has left the vicinity of your face after kissing you. He will then spend 5 minutes generating a substantial amount of laughter from you by 1. Acting very homosexual-attitude about the situation and 2. Showing you how crazy it makes you look.
When kissing my girlfriend last night she sat there without returning the kiss. She did not even respond. I pulled away and after about 15 seconds of just looking at her she made the sound of a kiss and a slight purse of her lips. Apparently there was an invisible man between us or she is just crazy. That is when I said "That was a Delayed Reaction"!

The act of either not having fast reactions in general, or delaying your reactions on purpose. May be shortened to DRS. Another word for this is "being a lazy piece of shit". DRS is normally present in people who couldn't give two shits about the world around them, even their friends.
Example:
1: Dude, why did you let the ball go into the goal?
2: What do you mean?
3: Dude, I think you have Delayed Reaction Syndrome
2: I'm not that lazy
1: Then why didn't you save it?
2: I don't know man
1: I think you're just a lazy piece of shit
3: For real
