Tinkerbelling is when a pixie stick is poured into someones anus and is then eaten out buy another person. normally a female since tinkerbell was also a female. if the person receiving would pass gas creating a cloud of pixie dust, this would be referred to as "fairy dusting."

Last night i fairy dusted my girlfriend. it was an awkward breakfast.
