I know how to say it, but I'm not exactly sure how to spell it. I'm pretty sure that's correct. Now to the meaning: Lo que sea means "Whatever." You can use it in a variety of ways.
1. "Boricua,cubano,negro! Lo que sea, ya tu sabes!" Pitbull (rapper) is saying, Puerto Ricans, Cubans, Blacks, whatever, you know! (From the song What You Gon' Do (Latino Remix))

2. Girl: Que quieres hacer? What do you want to do)
Boy: lo que sea...
Because we know guys don't really care.

3. Girl 1: Tu mamas en vida! (You suck at life)
Girl 2: Lo que sea pendeja! pendejo
