Halo 5 Forge Call sign is offensive

Hi Halo team,
When I created an account the system generated a call sign KULO for my user EvJet.
KULO is pronounced exactly as -Yoink!- which in Spanish means -Yoink!-
I found this to be offensive and need this call sign changed to something else such as WRRN or anything else.

Kind regards
Evan Peace
