GirlsFriendFromLastNight: Oh my god how was your date last night?
BottomedOutGirl: It was great up until about 4am. We had dinner, drank a shit load, but when we had sex he bottomed out!
GirlsFriendFromLastNight: Damn girl! Once you saw that dick of his you should have told him about that shallow pussy of yours!
Used as a way to describe the experience a person has with an airbed. As in the airbed is so deflated that your ass is touching the ground while attempting to sleep on it.
Hey man how was your airbed last night? "Aww man it was good the first few hours but then at like 4 AM I bottomed out."
You have bottomed out when you sit down in a port-a john and the mound of shit and paper is so high that your ass and sometimes your junk touches the top of the pile. This usually happens during high risk activities like sitting on the seat of a port-a-john in the dark.
I had to shit so bad that I didn't look in the hole before sitting down-I bottomed out! I knew it was a going to be a bad day when I felt that mushy mound of shit connect with my ass hole and balls!
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
