You clearly don't know anything about football.
Any person (usually a player but occasionally a coach and very rarely one or more spectators) acts or speaks in a manner deemed to be intentionally harmful or especially objectionable by the game officials, or by rule. Unsportsmanlike conduct is a non-contact foul; if contact is involved it becomes a personal foul. Examples include verbal abuse of officials, and taunting, which, since 2004 in the NFL, has included any "prolonged and premeditated celebrations" by players.
