Instead of saying "Rediculous" sounds better when said out loud. (Re-Donk-U-Louss)
Mainly used to either sound like an idiot, or just sound like you know bigger words.
i,e:

Ariyth The Pony- You're so REDONKULOUS!
Donkey- ._.

Annoyed Teenage Girl- Ugh mom, you're so redonkulous!
Mom- Can't you say 'rediculous'?
Annoyed Teenage Girl- Pfft, mom. No one says the real words anymore! >:l
