Do you have a catch-phrase?

[Mulholland]

Oh my that's one hell of a catchphrase

No, no catchphrase. I sent off for a permit for one back in '83, but have yet to hear from them about it.

"Was that supposed to hurt?"

[Webby]

"No worries" and "Yeah, whatevs" seem to be mine. I've been very tempted to change the first to "No need to worry" though. >.>
Cupboardy, ADAMMM and I have never seem to be pretty major catchphrases also.
