I hope this one gets translated >///<

here's my translation analysis
"itte yarou" written with the "go" verb kanji and an odd conjugation that implies "let's go" emphasis
"ja nai" normally translated as "it isn't" I'm fairly confident in this context it stands for " don't say it like that!"

So I'd go ahead and add the note : "don't just say "let's go in" like that!" but I'm sure there are more proficient translators in the site who'd find a better way to put it.
