Ice battles are when two hypebeast's show off their wrist and neck jewlery, such common items worn are fake rolex and yeezys.
Germain : "check out my new ice"
Logan : "That shit faker than ur instagram check this out" ( whips out his off the shelf yeezys and new rolex )
Someone in the croud : Its an ice battle!
*The cycle continues until one person runs out of shit to show*
