A rough handjob given in a dirty alleyway, with the penis wrapped in tin foil wrap, much like a kebab.
For just $150, you can get a quick Wan Chai Handshake behind that kebab shop on Friday nights.
When you give handjob in a narrow stinky alleyway after wrapping the schlong in aluminium wrap.
Oh man, last weekend I gave Nicky a wonderful Wan Chai handshake!
