Friends who are kindred spirits, think alike, or connect on a platonic emotional basis based on their world view. The term is similar to soul mate, but refers to two people who think alike in terms of religion, politics, and other topics without being romantically involved.
Jim and Sarah saw eye to eye on just about everything, even more so than with their spouses. They were true soul buddies.
A variation on the word "abscess." An abscess is a tender, inflamed mass-like collection of pus in the tissues of the body in response to infection. An assbscess is a collection of pus in the soft tissues of the gluteal region or posterior pelvis. It can be associated with the rectum, anus, gluteal muscles, skin, and/or soft tissues of the buttocks. It is posterior to the bladder and prostate gland in males and vagina in females. It does not involve the legs, and does not involve the genetalia.
A very tender infected mass in the buttocks near the anus would be an example of an assbscess.
