Is your child texting whilst using vim?

rofl - replace current char with o and find l

brb - replace 1st char of previous word with a b

lmao - move a bit then edit next line

imo - type mo

nvm - go in to visual mode

wtf - move to next word

The above is the peak of "content" from the blue bird site. Apologies but that's as good as it will get.
