In Portuguese we don’t use many acronyms, but we have shorter versions of words with the vowels removed or things like that. When people tried to use acronyms we ended up with “fds” which some people read as weekend, others read as “fuck it”. The only other acronyms I can think of right now are all for offenses such as fdp (son of a removed) and cdf (“ass of iron”, very old term for calling someone a nerd).
