A doker is a poker donkey mule who can not lay down any pocket pair. Dokers usually like to see many flops and continue to chase any draw no matter what. A typical online mule stable (online poker room) has numerous e-donks (dokers). Dokers increase in amount at lower stakes and are somewhat reduced at higher stakes. Dokers found at higher stakes provide maximum entertainment value and are shark-scoped at loss of thousands of dollars.
"that freakin doker called me down with pocket 3's!", "This table has so many dokers", "If you dokers wanna see it, I'll make you pay to play."
