when your friend is going out with another person, and they invite you along for the sole purpose of making sure the third person doesn't think it's a date.

in effect, your friend asks you to come along, just to defuse the sexual tension and make sure nothing happens without them having to verbally reject the other party.

note: Sex Buffers work best when you and the third party are of the same gender so they don't try to invite a 4th person to make this into a Forced Double Date
