Jordyn Woods can't handle her booze and that's why she was down to make out with Tristan Thompson and blow up her relationship with the Kardashians ... that's her story, anyway.
Sources close to Jordyn tell TMZ ... she has been begging her ex-bestie, Kylie Jenner, for forgiveness ... ditto with Khloe. And, while she admits she made a stupid decision ... we're told she's blaming it on the a--a-a-a-a-alcohol, as they say.
We're told Woods was wasted before she even went to the house party where witnesses say she snuggled up to Tristan.
