A particularly useless person whose attempts to contribute in a group effort often hinders or doesn't contribute to the success of the group; ball-trackers fake work to get credit or to avoid of the consequences of doing nothing; originated as a pinball term when there are three people who all want to participate (one right flipper, one left, one ball-tracker who follows the ball with his finger)
"I'll be right flipper, James you're left, and Jacob, if you reallywanna play you can be ball-tracker."
A “Ball Tucker” refers to a male who places their scrotum as well as penis between their legs as to hide their crotch bulge in order to look more like a woman. This term is usually reserved for drag queens, transsexuals, cross dressing heterosexuals, and perhaps the mentally unstable.
