An imaginary figure that has illusion of a large volleyball block when playing on a standard 8' height men's net. The reality is that "Rob Roof" is really only 1/4" over the net and was able to block the hitter merely because the opposing setter didn't set the ball high enough.
Occasionally, "Rob Roof" will block someone with a vertical 10 times of himself and will react in a frenzy, jumping around, yelling, and basically making a fool of himself. This phenomenon is known as little man syndrome
It is best to just smile at "Rob Roof" when he is acting this way and say nice job rather than enraging him, otherwise you may risk being put on his tea bag
Damn, Rob Roof is going crazy over there at the block he just had even though we're playing on a women's net and he just stuffed a 9 year old girl.
