Cocktail. Three shots of vodka in a pint glass of ice, then fill the rest of the way up with Smirnoff Ice.

A tool that helps when you have drawn too much crap into your math notebook. Does not erase mistakes that you have done in life so do not rub it into people or exam results from a math test because the only thing you can do is draw. Pretty sad. :(

bereft of doubt
just a little too humble
to shout it out loud
okay?
I can erase all the fah kin voy ces in a brain
I can bring back piece a gain
you better believe what i sang on that chune
we will be two get her first of june
in no time you will feel my love
and flow fine with my feathered dove
in. no. time. you will be my one
we'll grow pines in a field of oaks.

Eraser is something you use to erase something. You can only erase things by pencil.

an eraser is a piece of soft rubber or plastic used to rub out something written.
