gowobuhip

Short for "Gorilla Wolf Bunny Hippo" which would in emojis be "🦍🐺🐰🦛" which on Huawei phones have the colors black, gray, white and purple. Those are the colors of the asexual flag.
If your friend texts you this, they are just declining a make out with you because they are a pussy.

"Wanna make out?"
"... Gowobuhip."
"Man you're so boring bro"
