"I Seriously Hope You Guys Don't Do This"

A meme that originated on the 4chan board /sci/ in 2011.
Often accompanied by a picture of George Costanza from the show "Sienfeld" with a perplexed look on his face.
Used to show contempt for a statement made by someone often on an image board.
Often preceded with a ">" to make the post greentext and the year.
OP: "Should I get a degree in Philosophy or Psychology?"

Reply: ">Getting a degree in the humanites
