when your group of three (threesome) is spontaniously joined right before you tee off on the first tee by a typically annoying person with no one else to play with. This phrase is derived from but is not making fun of pro golfer "Vijay Singh."

2. when your group is held up by a single player on the hole in front of you or if he/she jumps in front of you right before you tee off
