Skanky Dechanky
A skanky dechanky also known in china as "ah shit" is where a 89 year old white male waxes his entire body, hops onto a baby blue BMX bike and takes off down a 1500 ft. mountain, whilst the wheels lose traction to the ground, the males hairless decerped body flies into a 23 year old Harvard graduate and goes to town.
God damn shawty, you really pulled a fat "Skanky Dechanky" on that science test last period!
