Mamluki is a word used to refer to over-age persons who play for a sports team in high school. For example, a talented over-age, college, or alumni student who has been bought to play for a school's football or basketball team to give it a competitive advantage.
It is illegal for high schools in Kenya to register non-students to play for their school team but some schools do find a way of evading the rules.
Mamluki is sometimes spelled as Mamuluki.
