Eroge

In order to distinguish themselves from other eroge makers, some of them have been doing interesting things with promo material. For example, you can download promo material used in shop posters together with transparency enabled PNG files from the site for ChuxChu Idol (click on the "download" link in the left column).

The makers of the up n coming eroge Oppai Baka (meaning erm... "Boob Baka" (Oppai(おっぱい)means boobs)^^;) have been doing something rather interesting with their promo material too. The picture you see is some promo material featuring one of the girls from the game. The chest area is made of soft squeezable material. There is a sign attached that says "Feel free to squeeze all you want!" (Image from Akibaos.)

"Momi-houdai"(揉み放題(もみほうだい)) means to "squeeze as much as you want." Adding the word "houdai" on the end of a verb means to "do as much as you want" (of that verb). So for example...
To eat = Taberu(食べる(たべる))。
To eat as much as you want = Tabe-houdai(食べ放題(たべほうだい))。
To drink = Nomu(飲む(のむ))。
To drink as much as you want = Nomi-houdai(飲み放題(のみほうだい))。 You usually see "Tabe-houdai" signs outside some shops meaning that you pay someting like 1,000 yen to eat as much as you want.
