Celebrity nicknames given by audience.

Genuine question: why does the audience have these weird “nicknames” for celebrities? To name a few, there’s:

SRK = Hakla Khan
Alia Bhatt = Churalia
Deepika = Cheapika
Salman Khan = Selmon Bhoi
Sonam Kapoor = Sodumb Kapoor
Ajay Devgn = Vimal Devgan
Ranbir Kapoor = Wigbir
Karan Johar = Naag Johar [or something like that]

Now I know how some of them got these nicknames. Alia because she apparently steals films. I may be mistaken, but I think Deepika’s has got to do with her being slut-shamed. Sonam because of her interviews. Ajay because of his pan-masala ads. Ranbir because of his hair transplant. If I’m not mistaken, Karan’s has got to do with him favouring nepos.

I don’t know how SRK and Salman got theirs, so I’d like to ask what they mean.
