A threesome, but with 6 people instead of 3. Usually only happens when every participant is either really drunk or horny.
"I must've had 1000 gallons of beer that day. We were all so drunk at that point that when we got home we jumped in bed and had a hexasex. Jack forgot his condoms though, so now my girlfriend Melissa is pregnant."
