You shouldn't advocate lumping four tropes unless you're willing to help with the work.
I like what acrobox said. They seem clear to me. In fact, this reminds me of the time when someone couldn't tell the difference between Thou Shall Not Kill
and Even Evil Has Standards
. Both pages are detailed and the later specifically mentioned other types of standards besides killing and yet the comment came up.
To further tell them apart, I'll add my two cents: there's a hero/villain distinction.
Bully: Often happens to
a hero. This demonstrates their restraint in regards to petty jerkasses and/or set them up as a woobie.
Flip: Often used by
a hero. This demonstrates their courage in the face of a much greater Power Weight foe. The page also says it's used as a delaying or misdirection tactic.
Taunt: Often used by
a hero. This is more foolhardiness. It may be part of a Hope Spot
Mugging: Often happens to
a hero. The page points this out; ", The Hero is held up while going about their business". Also-Ignorance. All the other tropes involve a degree of knowledge about the target. This is very clear about the ignorance.
