In Urban Dictory, one of the definitions of "love" is:

LOVE

The most spectacular,indescribable, deep euphoric feeling for someone.

Love is an incredibly powerful word. When you're in love, you always want to be together, and when you're not, you're thinking about being together because you need that person and without them your life is incomplete.

This love is unconditional affection with no limits or conditions: completely loving someone. It's when you trust the other with your life and when you would do anything for each other. When you love someone you want nothing more than for them to be truly happy no matter what it takes because that's how much you care about them and because their needs come before your own. You hide nothing of yourself and can tell the other anything because you know they accept you just the way you are and vice versa.

It's when they're the last thing you think about before you go to sleep and when they're the first thing you think of when you wake up, the feeling that warms your heart and leaves you overcome by a feeling of serenity. Love involves wanting to show your affection and/or devotion to each other. It's the smile on your face you get when you're thinking about them and miss them.

Love can make you do anything and sacrifice for what will be better in the end. Love is intense,and passionate. Everything seems brighter, happier and more wonderful when you're in love. If you find it, don't let it go.

One word frees us of all the weight and pain of life:

That word is love.

-Sophocles

Urban詞典關于愛情的定義是：

愛情

對于某人的最美妙的、最不可言狀的、最透徹肺腑的愉悅的感覺。

愛情是一個具有無限魔力的詞。當你們墜入愛河時，就始終想要呆在一起。而當你們不在一起時，就會想著呆在一起的情景，因為你需要那個人，如果沒有對方你的生活就是不完整的。

這種愛是無條件的關懷，它沒有極限，也不附加條件：全心全意地愛著某人。它是在你用生命去信任對方的那個時候，是在你愿意為對方付出一切的那個時候。當你愛著一個人時，你唯一想要的就是能讓對方真正地快樂而不惜任何代價，因為你是多么地在乎著對方，因為對方的需要總是優先于你自己的需要。你絲毫也不掩飾自己，能告訴對方任何事情，因為你知道對方接受的就是你現在的這個樣子，反之亦然。

愛就是當對方成為你睡覺前所想的最后一件事情的那個時候，是當對方成為你醒來時想起的第一件事情的那個時候，是溫暖你的心房讓你回歸祥和的那種感覺。愛情包含了你向對方顯示關懷和/或熱愛的渴望。

愛情能讓你為獲得更好的結局而做出任何事情、付出任何犧牲。愛是熱烈的，愛是激情澎湃的。當你沐浴愛河時，一切看起來都比平時要更明亮、更歡快、更美妙。一旦你找到它，就不要讓它走掉。

有一個詞使我們擺脫了生活中所有的負擔和苦痛：

這個詞就是愛情。
