U.D. Names

When people put names/friends' names in the Urban Dictionary just to send it to them and say "OMG This description perfectly describes you!" and then they freak out and show their other friends and maybe post it on Instagram or Snapchat or something and they'll never know that you were the one who posted it!!!

"OMG you know those U.D. Names?"
"Yeah?"
"I FOUND YOU AAAAAAH OMG CUTIE!"
