Irony

Haha, yes, plenty ironic.

This poem is too rhyming. I realize that you're trying to achieve a sarcastic tone with the rhyme and wording, but it doesn't seem to work. I think it doesn't work because you seem to be bent on using obscure words, but these obscure words really don't add anything to the poem and just drag it down. Shakespeare has a sense of fluidity in his works and, with a couple of rereadings his poems are wonderfully light on the tongue. This, on the other hand, seems to roam the dungeons like an eternally chained ghost.

Reread this a couple of times. Don't focus on your rhyming as much--focus on making your meaning come alive. Then it'll get better.

Charms is in quotes because they aren't really all that charming

brusque - blunt in manner or speech often to the point of ungracious harshness

scathe - To criticize or denounce severely

knave - a tricky deceitful fellow
have you never read Shakespeare? He uses knave as an insult all the time.
