Is Urban Dictionary my mom?

"Is Urban Dictionary my mom?" Is asked when someone is a troll, or when dictionaries look for their long-lost mother from their DNA Tests. The less common reason why this is searched is from when a parent tells their child Urban Dictionary is their mom. The answer to this question is no, Urban Dictionary is sadly, not your mom.

Kid: "Mom are you really my real mother?"

Kid's Mother: "No son, Urban Dictionary is."

Kid: "Okay ill ask Google, "Is Urban Dictionary my mom?""

Or

Sad Troll: "I'm going to ask the internet "Is Urban Dictionary my mom?", I'm going to troll Google!" *Note: Google doesn't actually care
