I had to look that up...
The old videos make me want to stab people.
When I was a teenager, it was cute. I didn't hold a hatred nor obsessive love over her like 4chan, then she came back and revealed her normal self and I was like... "Yeah." know what I mean?
no, I don't know what you mean.
Would waifu.
Yeah, see that's the thing I don't get, but maybe it's that I'm not crazy.
Waifu is a memetic reference to Azumanga Daioh's Kimura-Sensei who has a thing for his female students, said students find a picture of a woman in his classroom who he refers to as "my waifu" or "my wife."
Mai Waifu is a meme, usually referring to a female anime character who a lonely male is pretending is their wife or girlfriend.
"Would waifu" is just an alteration of the meme simply saying you'd pretend to be married to the woman you're referring to.
