Fillet and Loin.

The names are based on meat cuts, which she likes a lot. But it do says roosu/rousu, yet it means loin - http://ja.wikipedia.org/wiki/%E3%83%AD%E3%83%BC%E3%82%B9 (check also the linked english page to it). Also there is mention on the page for "roast" from where this roosu/rousu word came. But it seems it's used for sirloin/loin and similar meat cuts.
