> chimps f.x. Just a small note, that abbreviation seems extremely rare to me. You might have better readability by saying "e.g." which means the same thing, or just writing it out. It took me a while to figure out whether you were referring some body part belonging to chimps or something
Depends on where in the world you hail from originally. I have also seek "fks" to mean the same thing. More common with non-native English speakers.
It's probably a feature of non-western English varieties. I've never seen "fks" used to mean "for example" and would never imagine that that's what it stands for.
