similar to the phrase "cheseburger" someone who is feeling "japanese show smiley" is simply put: someone who experiences supreme happiness for whatever reason. they could be so happy because they got a job, they found out that their girlfriend ain't pregnant, or because they just got laid. the reason for becoming "japanese show smiley" varies from person to person.
jane: i got bad news for you jake, i'm not pregnant...

jake: wtf you talkin' about girl, i'm fucking happy as i ever been!!!

jane: god jake...why you gotta be so "japanese show smiley". i thought you wanted to have a baby with me.

jake: naaa girl, just said that to get some of your yum-yum-yummy...
