The Davidposting refers to either of this two situations, as long as they occur for the majority of one's messages:
(1) The act to send ironic messages which, with my way of thinking, seem kinda possible
(2) To say something purposely false, to tell bullshit
(1) I masturbated to the Gormiti toy line
(2) Yeah I wanted to decorate my study for Christmas this year (hates Christmas)
Both are cases of Davidposting
