Wotas are fans of idol groups.
The word Oshimen (推しメン) comes from "oshiteru member" ("The member you support"). It's the term used to describe a fan's favorite member. Even though oshimen generally refers to only one member, many fans have more than one oshimen per group (The favorite member among the oshimen is usually referred as Kami-oshi). Sometimes fans change their oshimen (Oshihen).
The term Oshi (推し) applies to fans. For example, if a fan's oshimen is Yokoyama Yui, he is a Yui-oshi. Another example is the song "Team B Oshi" (Team B Fan).
DD and MD
DD is short for "Daredemo Daisuki" ("I love anyone"). It's a term used for fans that like many members in a group.
MD is short for "Minna Daisuki" ("I love everyone"). It's a term used for fans that like all the members in a group.
Hako-oshi (箱推し) refers to a fan who supports an entire group rather than a single oshimen from that group.
Light Sticks (サイリウム Psyllium), also called Penlights are used by wota at concerts. They are short plastic rods that glow in the dark. Fans wave them during performances, sometimes in unison, in order to show support for the members.
Usually, a Team or Group's official color is also their light stick color. For example, supporters of Team A wave pink light sticks, since Team A's official color is pink.
In SKE48, each member has her own light stick color combination. For example, Matsui Jurina has asked her fans to wave one orange and one green light stick for her. Some members of other 48 groups also have established light stick color combinations.

There are two types of Akushukai, Zenkoku and Kobetsu
Zenkoku Akushukai are when a group of around 20 AKB48 group members participate in a handshake event in a large city somewhere in Japan. You shake hands with all of the members in that certain row you choose, instead of an individual member. There is also a mini-live event at these events.

Kobetsu Akushukai (also known as Dai-Akushukai), are events in which all members of AKB48 and it's sister groups are present. In this setting, fans get approximately 10 seconds per ticket to spend with a specific member. Fans are allowed to combine tickets to spend multiple minutes talking to the girl.
The tickets to the Kobetsu Akushukai come with the Theater-Edition copies of singles. However, you have to apply online and pre-order these copies via Chara-Ani when the handshake applications open. This is usually about 1 month before the release date.
Shamekai (Also known as 2-Shot events) have the participation of all members of AKB48 and it's sister groups. On this events, fans are able to take a picture with their favorite members. Tickets are included on albums, that are usually more expensive than singles.
