Slang
What does NSA mean?
NSA means no strings attached — casual sex or fun with no expectation of a relationship.
Also: no strings attached
NSA stands for no strings attached, signaling that someone is after a casual encounter without romance, commitment, or follow-up expectations. It sets the terms clearly on a profile.
Being upfront with NSA is a courtesy: it prevents mismatched expectations and lets people who want the same thing find each other. Casual still means consensual and respectful.
Even NSA meetups benefit from a quick chat about boundaries, safety, and what each person is up for. Casual does not mean careless.
"NSA fun, nothing serious."
