"Me me big boy" is a heavily used term first popularized by Jack in February 2017, following a video upload on YouTube where Jack repeats the phrase "me me big boy" during a conversation with a telemarketer, who, after Jack said "me me big boy" a third time, hung up on him. Also, Jack posted a comment in February which reads "me me big boy".
In March 2017, Jack uploaded a Yesterday I Asked You video, but the upload did not follow with the usual YIAY format and instead, everything, including the opening and ending phrase, the theme song and the comments were all read by Jack as "me me big boy". He also used different tones while reading a comment and also read the comments in different situations (i.e. dialogue, asking the judges to rate the comment etc.) albeit the fact that every comment was written the same.
