Although the above
definition is correct, there is another situation it applies:
Nuts to Butts refers to 2 males riding together on a motorcycle or scooter - often times because the passenger is too
lazy to walk to class so he hitches a ride on his buddy's scooter. Guys 2-up on a crotch
rocket is the WORST way!
Looks at those 2 dorks riding
nuts to butts to class.
Guy Passenger: "dude I need to save gas
money, can you take me on your bike to the store?"
Rider: "
nuts to butts? hell no"
