A trolling motor for fishing lets you putter along slowly at a snails pace. You're playing like a speed boat washing him away in your wake.
I've heard of fat guys being called slim and tall guys shorty , maybe he called you troll because you're rocking his boat too much.
Nah, just a sore loser. Besides what you do with your shot clock is up to you. Personally I love a fast paced match.
