An ellipsis golfer is a person who willingly places themself into situations which are simple to solve for them (but may not be so from the perspective of another person) in order to brag about their success. Background (golf): If the tee and the hole in the game of golf are placed at the two focus points of an ellipse respectively, then it does not matter in which direction the golf player hits the ball, as it will always fall right into the hole given sufficient speed.
Look, this dude is telling kids that their homework is a no-brainer. He is such an ellipsis golfer.
