A slang term used by non-Asian people to describe Asians. Not used in a derogatory manner, but more as a way to tell your friend about how you want to bang the cute Asian girl in your stats class without referring to her as the "Asian" girl.
An adjective used to describe a smile as extremely wide and mischievous, cocky, or malevolent looking--"a Cheshirian grin". Derived from several adaptations of Lewis Carroll's Cheshire Catcharacter in Alice In Wonderland, including the Disney version.
