Another way to say hello when someone hasn't given an answer/reply in a suspiciously long time. Usually used in the context of if said person had replied not long before.
*person hasn't replied to text after long conversation for 10 minutes* Yullo?
*you have been cave mining with someone and you know there are rabbid creatures possibly in said cave* Yullo? YU-LLO???
