When an annoying girl on tiktok posts about doing something random that has other implicit meaning and gives no further explanation so people are stuck wondering what her made up shit means.
This girl posted about checking a man’s left hip. She needs to get a life and stop wasting people’s time. Although all these people have time to waste if they are on tiktok.
"Checking the baggage" refers to the act of arranging or rearranging the contents of one's trousers (i.e. penis and testicles) in order to ensure's one's own comfort while sitting, standing, playing the piano, etc.
