To make someone feel gullible and embarrassed after he/she has believed your nonsensical and facetious commentary, statements or reactions, which were meant in jest but also to get a rise out of him/her
Why do you love to gullibalize me? I can't tell whether you're serious or not and really you're just teasing me!
