My brother and I tried something similar in high school (though not swearing, because the person who was [verbally] bullying my brother was one of the teachers); we spent hours picking choice bits out of the OED for my bro to use on him ("yes, Mr. Teacher, I think everyone would agree that you are indeed a caitiff and that your lecture was particularly adiaphorous today"). The teacher was so pompous that he wasn't going to admit that he didn't know the words, so he wasn't ever any more than perplexed and wary (we didn't actually want to hurt his feelings), and my brother had the inner glow of knowing that he'd gotten off a nifty, and felt like he'd restored some balance in the cosmos.

PS: adiaphorous=inessential, immaterial
caitiff=base, mean, despicable wretch; miserable person, one in a piteous case
