when u go up to someone from behind during
recess (gender does not matter, but comedy effect works best on younger than 10 yrs,
clueless and female victim) and suddenly
squeeze their
cheek (in a rather
gentle way) and shout "buji!" (try to make that sound baby and
kawaii)
Warning: do not use on
overly popular girls for they will
probably get
annoyed and report you to da
teacher
