Be it syntax or semantics, for literary effect, or simply to piss someone off, what do you choosedly abuse?

I am a fan of the occasional tautological statement for poetic flare. Although I admittedly lean away from it since my writing is no longer for an audience that requires x amount of words. Example: abundantly opulent.

Horrid overuse of the ellipsis... tehehe. Why not...?

And as exemplified in the opening statement: incorrect application of suffixes to create a more lyrical flow.
