look up any word, like fleek:

DLN
Don't Look Now: when you're talking about someone nearby but don't want them to know; you must say it while looking at the target but not OBVIOUSLY just in case your friend looks and spoils the moment. Your friend usually looks AFTER they have passed.
DLN but those shoes are hideous like OMG!

Dirty Little Nigger. To be used in situations where saying the n-word is inappropriate.
I went to Popeye's Chicken and there was a bunch of DLNs working there.
