What you say when something funny or embarrassing happens, you pretend to have a camera phone in your hand and say zoom in zoom in! oh dayuum!
Can also be used when two people are fighting
-twokids are fighting-
Me and another friend: ZOOM IN ZOOM IN! OH DAYUUM
Its the same as damn, but you pronounce the sound of the "Y". You usually say it after somethingdramatic happens or when some gnarly stuff goes down. The word "son" is put after it lots of times so it makes it sound more buttery.
*some dude dumps his girlfriend*
random on-looker" DAYUMN SON!
*a rapper throws down a sick rhyme"
everyone: DAYUMN NIGGAZ!
