The act of a person sucking a cock by proxy for a reward.
Dude!, can you proxycock this guy so I can get this car!?

Being exposed to another males naughty bits via proxy when an infidel who previously performed fellatio exposes an unsuspecting lover or confidant to their ejaculate without Your knowledge or consent.
"Have You ever sucked a cock? No, but I have sucked proxycock before when My ex sucked the cum out of a car washers cock in her office at the hospital and kissed me with her tainted lips when I got home from work".
