GaHorse - A giant necked donkey that thinks it's fancy and won't stop

A giant necked donkey that thinks it's fancy and won't stop showing off.

My cousin's pet GaHorse won't stop eating my homework.

I saw a GaHorse in the mall and it yelled at me for not tipping it.

My teacher said I was a GaHorse for talking too much and wearing socks with sandals.
