Done Stuck on a word NEED HELP!

[b-werx]

I'm currently working on Magikano chapter 12
And I have hit a snag, in page 80 of Magikano vol.3, a lady approached Haruo telling him rumors about the young pastry chef that Chiaki is meeting secretly.
One of the things she mentioned is "三股" (read as MIMATA) I already looked it up at Google, but all I keep getting is "three pronged fork" which is "sanmata" not "mimata"
Can anybody help me with this? The conversation of the whole page is pasted below for reference:

Lady 王子って女の子すぐにポイ捨てするからねえ~~~~
Lady つねに三股くらいかけてるみたいだし
Lady ハアー 顔はいいんだけどねえ
Lady それにあのウワサ。。「女体ヂコレーションケーキ」？ 強要するってさ！
Lady しばったうえになめまわすらしいよー
Lady あんなカワイイ子が花を散らすなんてね~~~
Maika ？お兄ちゃん？
Haruo ボ... ボクが
Haruo 一番 恐れていたことが！！

I am already familiar with "女体" or "nyotaimori" the famous female body dish, but I'm wondering is "mimata" (三股) also a food fetish of some sort?

PLEASE HELP!

Thanks for the enlightenment, it's the definition that is best suited!

suteru is to discard. context is important with translation, since without context, it doesn't really mean anything. You know it's related to a relationship if the conversation has been about dating.
