HDA

home display of affection similar to pda but at home,
when your parents show kiss or make-out in front of you or hda.
acronym for “hammered dog -ss”. completely lacking in aesthetic merit, extremely ugly, displeasing to the eye and viscera. the resulting visual summary of an already homely subject after a losing impact with something large, heavy and iron.

may also be used to express feeling under the weather, i.e. “i feel like____.”
m: that girl was pretty cute last night man, it’s a shame i wasn’t able to go home with her.

b: on the contrary, she had the beak of a falcon, no chin, and a dusky mustache. she looked like hda, (hammered dog -ss.)
head disk -ssembly, the part of a computer’s hard drive which stores the data.
typically when a drive experiences the click of death (ake the omgwtf i just lost my data) noise the head comes in contact with the disk due to the collapse of the micrometre thickess air bearing from contact with a particle, resulting in m-ssive damage known as a head crash.

normally the end result is a bricked hard drive, which is recoverable if you are lucky and have a couple of k$ to spend on data recovery in a clean room.

interestingly a hard disk will instantly crash if opened up and smoke blown onto the disk while spinning, useful for demonstration purposes but ruins the drive

sometimes a failed drive can be salvaged by the careful replacement of the head -ssembly from a donor drive, this is a last resort and can make things worse in most cases.
dude, your hda just went flatline. hope you have backups.
“hit dat -ss”
“ey’ man, i see you talkin’ to ol’ bird over there. hda or wha'”

“holy smokes, check out the hda on her.”
