Snow Crash by Neal Stephenson.
Here is the description from Amazon:
In reality, Hiro
Protagonist delivers pizza for Uncle Enzo’s CosoNostra Pizza Inc., but
in the Metaverse he’s a warrior prince. Plunging headlong into the
enigma of a new computer virus that’s striking down hackers everywhere,
he races along the neon-lit streets on a search-and-destroy mission for
the shadowy virtual villain threatening to bring about infocalypse. Snow Crash is a mind-altering romp through a future America so bizarre, so outrageous…you’ll recognize it immediately.
It's commentary is often funny and over the top. Rating = 4 of 5
-- It is a good read for all scifi fans.
