It's nonsensical or every creature to be goaded by normal words, though. Like completely nonsensical. There's nothing you or that fighter could say that would get me to rush you like that. The only way you or that fighter could do it would be with some sort of supernatural mind control.
Feigning to trip, giving you an easy kill over an otherwise fantastic opponent? Who jumps to his feat and impale you with a gotcha smile?
The limit of providing explanation to powers is that what is good for, say, human brigands or soliders won't work with a bear protecting its cubs or a demonic swarm of flying larvae with whom you share no language. I am split between letting player narrate (it forces them to do better than "I attack" or "I attack... with my sword! can I have inspiration for my flourished description?") and having wildly broad powers...
