Coined by Ryan Seacrest as a "sign-off" line. Possibly inspired by the 1960's television series "Voyage to the Bottom of the Sea", whose submarine was named the Seaview. When the captain was communicating via radio, he would sign-off as "Seaview out".
A way to end a conversation with your home boys; whether on the phone, texting, etc. It use to be "gay", but now it's funny and a smartass way to end the dialogue, and let your buds know that you are tired and need to hit the sack. Based on the radio DJ Ryan Seacrest's catchphrase, when he ends his show: "Seacrest Out."
I was tired of texting with Kurt, on whether Michigan State deserved to be in the Final Four, so I just ended it with "Seacrest Out."
