Ya = everything except the jiggly bits

Blonde #1 (drunk): So, he pulled like a total Jerry Maguire on me... he's all like: 'I love ya.' Does he love me or what? Like, is ya the same as you, or different?
Blonde #2 (drunker): I think it's like, deep, but not too deep. He loves ya, but not all of you. You know?
