wrangle, growl at
嘊 centers on verbal conflict: wrangling, arguing, or growling at someone in a heated exchange.
嘊 combines 口 (mouth) with 崖, which likely contributes the sound ガイ. The mouth radical suggests the meaning is related to speech or vocalization.
A mouth 口 beside a cliff 崖: imagine two people standing on a cliff edge, shouting and growling at each other in a heated wrangle.
For ガイ, picture a guy standing on the cliff, growling loudly: guy -> ガイ, and his growl echoes across the cliff.
