Ignore and carry on, saying you had a threesome seems more of a retaliatory response.
Such as "yeah i blew some dude" "OH YEAH ? Well I HAD a threesome, BOOM !"
If a girl is saying that casually it's absolutely a shit test, or she's trying to friend zone you hard.
My reasoning tells me it's a shit test, play it cool and calm, get the bang, and eject her immediately.
OR
Just go radio silent on her.
