Indicative: Adjective. Serving as a sign or indication of something; in this case also a poorly disguised pun.

Okay, so if owning a Porsche is indicative of peener size, what does that say about Nick Lachey with this diamond-encrusted toy car at the Hot Wheels 40th Anniversary Celebration? Hmm... If I had to guesstimate, I'd say old Nick here is probably hung like a hamster.

Oh, and by the way, hamster dick -- you might wanna go easy on those Baconators. I'm just saying.
