When used in its acronymical form, representing the terms "Doing" "It" and "Partner." A DIP is therefore a person with whom one engages in sexual intercourse/activities. The term can be used as a substitution for girl/boyfriend or in reference to an individual with whome one is only 'messing around.'
Yeah, I always see him with his DIP these days, never has any time for us.
Girlfriend?!? Fuck that, she's just my weekend DIP.
An amalgamation of 3 separate acronyms, POP, ASD, and AH, respectively standing for "Penile Organ Penetration," "Anus-Splitting Dick," and "Asshole." Thus, POPASDAH becomes "Penile Organ Penetration with the Anus-Splitting Dick in the Asshole." Useful when the term 'fucked in the ass' cannot be used due to company or etiquette.
I heard Davie gives Karen the POPASDAH every night, I wouldn't stand for it.
