A combination of 'whoo hoo!!!' and booty
Used possessively, as if the woman has some 'hootay' that she could give you, making her 'hootay' the sex
you want to have with her. Can also be applied to a male.
"Give me some of that hootay, mama!!!"
An alternate use would be this; the woman
has the 'Hoo', the man
has the 'Tay'; ergo the usage could be thus:
"I'll show you my 'hoo' if you show me your 'tay', baby
