What is the correct way to pluralize an acronym? asked about pluralising acronyms, abbreviations and initialisms, but is there a standard way to add verb endings e.g. -ing and -ed (what are these called?), at least in informal English?
For example, which of these is/are best?
- I'm SMSing her.
- I'm SMS-ing her.
- I'm SMS'ing her.
I know I can rephrase it to "I'm sending her an SMS." but I wish to use SMS as a verb.
- He FUBARed.
- He FUBAR-ed.
- He FUBAR'ed.
- He FUBAR-d.
- He FUBAR'd.
In the latter set, as the verb is actually the F ("foul", or something more explicit) — the expanded sentence being "He fouled up beyond all recognition." — should it even be "He FedUBAR." or similar?
