fr ong is a strong intensifier

“on god’s life I swear it”

Quite the shocking statement.

I read ong as a typo of omg, maybe I’m old now tho. But the 3 dead skulls suggests a high level of being made dead by whatever the original comment was, which combined could be translated into ‘quite shocking’ among other various meanings

I think the “shocking” part is communicated moreso by the sentence as a whole
