When some asshole only eats the good parts of trail mix or cereal, leaving all the nuts and healthy shit behind for the next chump.
Clyde: "Dude pass the trail mix."
Johnny: "No, I'm sick and tired of you only eating the M & M's."
Clyde: "Come on, hand it over."
Johnny: "No, I'm done with you lucky charmin' me, all that's left are the raisins."
