It's all slang. One of the functions of slang is to emphasize the attitude to a particular social group: students, schoolchildren, teenagers, drug addicts, mathematicians.

“Pahan” was relevant in the 90s, 2000s, (krim., jarg.) the leader of a criminal group; a criminal with power, authority; (jargon) father, parent; (jargon) head, supervisor, boss
More or less similar in meaning and actual “papik“.
**«Macho“ – often began to be used in a sarcastic sense, and therefore morally outdated, lost its original emotional color. Replaced with “* * Alpha“**,“Alfach“. ** Although these are also often used sarcastically.
Cool“ ” �** – still more or less relevant, but “cool“, “nice“, “nishtyak“, “top“**is used as a substitute.
