The term 'hewo' is basically the same as the word 'Hello', but said in a more child-like manner. (mainly used by furries and anime weebs) be careful if you use this term, you may not get friends.
Random Furry girl on Discord: ''Hewo STAR_PLAYER156!''
STAR_PLAYER156: ew. stay away from me- are you like; 5?!
Random furry girl on Discord: But the Urban Dictionary said you can use it because it's the same as the word 'Hello'!?
STAR_PLAYER156: Stupid girl. Didn't you read the rest of it?
