Tourette syndrome is a neurological condition involving involuntary movements or sounds called tics. Stress, excitement, and fatigue can make tics more noticeable - they are not intentional behaviours, and the stereotype that Tourette’s always involves swearing is inaccurate - coprolalia affects only a minority of people with the condition. The clip's appeal is the unusual, almost ritual-like combination of gestures - crossing himself, kissing the mic, and repeating it - paired with his visibly amused reaction. Commenters often describe it as a 'religious tic," although it is simply an involuntary Tourette-related tic that happened to resemble a blessing.
