Swearing in the name of anything besides Allah is prohibited
Oath is a solemn appeal to Allah to witness one's determination, or to emphasize a matter by mentioning a glorified one in particular. Glorification and exaltation are due to Allah Alone, therefore, it is not permissible to swear by other than Allah. Scholars are agreed that an oath must be sworn by Allah, His Names or Attributes only, and that swearing by other than Allah constitutes Shirk. Ibn Umar (radhi allahu anhu) narrated, 'The Prophet (sallallahu aliahi wa-sallam) said, 'Allah has prohibited you from taking an oath by your fathers. He who must take an oath, may do so by swearing in the Name of Allah or he should remain silent.'' [Agreed upon] Ibn Umar (radhi allahu anhu) also reported that the Messenger of Allah (sallallahu aliahi wa-sallam) said, 'He who swears by other than Allah, commits Kufr and Shirk.' [Musnad Ahmad]So, Gul should take that in mind and don't misuse swearing words, seriously.
People take wrong use of swearing because of lack of knowledge about it. It should not be promoted in the show also.
