To "bottom out" is when one is having sex and the penis reaches the cervix, or the top part of the vagina, and can go no deeper. This can be referred to as "bottoming out," or in the past tense as "bottomed out."

It can be either painful or pleasurable, depending on the girl and how extreme the bottoming out is.
Man, I was fucking this chick last night and she told me to stop cause my dick was so big I was bottoming out on her.
