戴耳機聽歌的時候，你是不是會看清楚兩只耳機上的L和R，然后分別把它們塞進對應的左右兩邊耳朵里呢？嗯，小編就是這樣的！據說，這也是強迫癥的一種呢！

Headphone OCD is a condition where you want the two earphones on a headset on the correct ears, that is, the left side is on left ear and right side is on right ear. If you put them in the wrong ears, you would feel very uneasy and would stop what your doing at hand to make them right.
Headphone OCD（耳機強迫癥）指用耳機時總想著要把L一邊放到左耳里，R一邊放到右耳里。如果不小心放錯了邊兒，你就會覺得特別不舒服，然后停下手里的活兒把它們給調換過來。

The OCD refers to obsessive–compulsive disorder, which is a mental disorder where people feel the need to check things repeatedly, perform certain routines repeatedly, or have certain thoughts repeatedly. People are unable to control either the thoughts or the activities. Common activities include hand washing, counting of things, and checking to see if a door is locked.
OCD是“強迫癥”的簡稱，這其實是一種心理障礙，患有此癥的人喜歡反復檢查一些事情，反復做一些常規的舉動，或者反復出現某些想法。這些想法或者行為都是人為無法控制的。常見的強迫癥行為包括：洗手，數東西，檢查門是否鎖好。

For example:

How can I get rid of my headphone OCD! What does it matter if I put L side in my right ear!
我怎么才能改掉我的耳機強迫癥呢！就算把左邊的耳機戴到右耳上又有什么關系呢！
