Kato,
Here's what the wikipedia page said:
Rubber band play is a term given to a sports gambling pick by the poster Brock Landers on sbrforum.com. Following these Rubber band plays will likely lead you to start bouncing checks, committing bank fraud, and delivering pizzas for gambling money. Another side effect of betting these Rubber band plays is having to hit your parents up for money to save your house and feed your kids.
