Sucker
Slang for a gambler who consistently makes poor bets or is easily taken advantage of. A “sucker bet” refers to a wager with a steep house edge or low chance of winning that inexperienced bettors might take.
Betting a 15-leg parlay for a huge payout is generally a **sucker** move – the odds of hitting every pick are minuscule, and the sportsbook holds a big advantage.
