Person with sexy hands will drop or break everything that is touched. Will crash a computer by pressing one button on the keyboard. The person is useless at ball sports (couldn't catch a flu during a pandemic). For a guy with sexy hands it can take years to get to second base with a girl as he always ends up accidentally injuring them (eg: accidental punch in the head when taking sweater off, will never be able to take bra off, is the type of person that will accidentally head butt a girl when attempting to kiss her, etc)
