That concert was terrific.

That was so scary, it was terrific.

Lindsay: Were you scared to come into our apartment?

David: huh? what makes you say that?

Lindsay: It had a super scary pumpkin outside and spooky spider webs!

David: oh yeah. i was terrified. i forgot i guess.. probably a side effect of being so terrified

Lindsay: Hmm...perhaps. I'll go with it...amnesia related to terrification. That's my nursing diagnosis.

This ice cream is terrifical

You's guys are so terrifical.

Appear brusque and unintelligible to equal terrification.

Me: "You know what? You're singing's terrific."
Ex Gf: "Thank you!"
Me: "That wasn't a compliment, bitch. I was mixing the words terrible" and "horrific" to make you seem stupid, you whore."
