Casino Pressure
An influence similar to peer pressure, caused by any casino when its sheer magnitude of slots, tables, people gambling, etc induces you to gamble, especially when you had no intention of gambling at that moment. Usually, but not always results in losing money.
After losing $300 the first night playing blackjack, I swore to not gamble for the next day, but a few hours later the casino pressure got to me and I ended up losing another $300.
