There must be something in our DNA
Or in our language roots or ABCs,
That make us love our shortcuts. MLA
Provides just one of many SOPs:

You needn’t spell out acronyms like RADAR-
Like SCUBA, it’s in common enough use.
Pronounce as words those entities like SPAWAR,
To find their meanings, check their FAQs.

With chatting slang, just shrug and LOL
Or say say that you were just now AFK;
You’re only ever truly SOL
When lacking context equals IDK.

And while such things will work for A/S/L,
ILU is much better IRL.
