A man (usually white or another non African American Race) who enjoys having sex with (or "jamming") black women. They are referred to as Kool-Aid Jammers because they are jamming people who enjoy Kool-Aid alot. There is not a fried chicken jammer, however, because that wouldn't be a funny play on words, and it would be stupid.
