Clearly, a typical UrbanDictionary boardroom meeting must reek of pretentious tats, excessive cursing, and skateboard epoxies -- pew! I would use this site sparingly, maybe for a slang synonym (at most). And even there, it's so childish and subjective.
I'd opt for sites like slangsite.com, peevish.co.uk/slang, Thesaurus.com, rhymezone.com, sentencedict.com, and etymonline.com for a more mature and professional inquiry.
If you're serious about your future, and not just looking to stretch your adolescence with delusional comradery, then avoid Urbandictionary all together.
