An incorrect romanization of the japanese, "Good Morning!". Ohayou is the correct spelling (the u is silent) and is the informal version of Ohayou Gozaimasu.

Ohayo is used among friends and people who are of similar age.

lil mad is like big mad but the opposite, you mad but not mad to the extent of pullin somthin

Japanese for "Hey"
More casual than Konnichiwa which means "Hello"

good morning in japanese, can also be said as ohayo gozaimasu
