What does Wallah mean?

Swearing.

By God. (followed by I swear or a synonym). For the identity politics muslim crowd, using the name of God in vain, i.e blasphemy, is comical in a way.

It has a different meaning in the UK, picked up from the Raj. It means a person but you link it to something else, eg  a rickshaw-wallah or, much used in Britain in the 1980s a dole-wallah (ie unemployed person).

Yeah although I think it's less common now. But you'll see chaiwala as a common name for an Indian cafe.

Edit: Looked wallahs up on Wiki and really like that satellite dish installers in India and Pakistan are called dishwallahs. Also quite like puncturewallahs for people who deal with punctured tyres.
