You are looking for Spintax ! That's how bots do comment-spam.

Example : "{|||Wow! |Hey! |Looks {nice|cool}! }{{I like|I love|Like|Love} {this|your}|{Very nice|Nice|Cool}} {photo|foto|picture|pic|image|img}{.|!|!!| :)| ;)| :D| <3}"

That’s not what OP asked for because it’s not optimized. You can e.g. optimize "I (love|like)" as "I l(ov|ik)e".
