'Hey, what time's the dorm curfew again?' '21:00.' 'Crap, I won't make it unless I run.'
Literal
'Hey, dorm [of-の] curfew [topic-って] what time [reminder-だっけ]?' '21:00 [feminine emphatic-よ].' 'Crap, run-[not-ないと] be-in-time-not [masculine emphatic-ぞ].'
Three-line casual dialogue across speakers. なあ is a rough masculine 'hey.' ~って is a casual topic marker, a colloquial contraction of は or というのは. だっけ is an interrogative reminder-seeking particle: 'what was it again?' やばい is modern slang for 'crap/no way/awesome' (context disambiguates — here it's 'crap'). ~ないと is conditional 'unless,' here implying a negative consequence. ぞ is masculine emphatic final particle. The speakers mix gender (よ feminine, ぞ masculine).
