What the hell happened last night?

me and a bunch of friends went to a friends house and got a keg and a half gallon of goose. we started drinking at like 11 and by 1:30 i blacked out apparently i was doing a bunch of stupid **** and i have no clue what it was nor do i know if it really happened. i had like 10 shots and 6 beers is it possible to blackout like this? or are my friends just trying to make **** up
