Ahh...actually that *might* be what he says. The second character after the "Da" is a "tsu" but it's smaller so I read it as being there for emphasis rather than a proper character in its own right. But "DATSU WAIFU" would make sense in that context :)

I'm very bad at Katakana as a rule anyhow. So that's probably the answer...

Good call :D
