The line comes from Good Mythical Morning, the long-running show hosted by Rhett McLaughlin and Link Neal, in a segment where Link straightens Rhett's hair. The moment works because it is unscripted in feel: Rhett is not playing a character, he is reacting in real time to having his hair pulled and heated. Short clips from the show are often lifted for soundboards because the hosts' banter is easy to reuse out of context, and this one survives as a compact admission of sensitivity that fits hair, barber and makeover videos without needing any setup.
