YO-HEY'S Nicknames

Daisuke Harada
"The Boss"

Reason: He's the leader of RATELS

Tadasuke
"The Boss's Mom"
"Okasan"

Reason: he has long hair and is round like a traditional Japanese woman, plus he is the one who usually sides with Harada, seconds the others, and carries them from the ring when they are injured. "Okasan" means "mother"

Hayata
"Wife"

Reason:  he and YO-HEY go everywhere together, HAYATA tends to agree with him, and also because HAYATA can be strict with him i.e. not letting him shake hands with people (HAYATA can also be very stubborn)

YO-HEY having to check HAYATA isn't looking before shaking hands with GurukunMask (who he called "Fish Face")
