I feel really stupid asking this but. . .

[Animeistro]

What does Gaara's tatoo mean, the one on his forehead?  

[Akikuro]

It means "Love".  

[enjay babe]

Love.

And combined with his name, means "a demon who only loves himself".

Which explains his characterin the beginning

It looks like a chinese symbol that means 'love.'  

[Animeistro]

That would explain it.
Thank you for the prompt replies.  

[YoshiMexico]

Japanese Kanji.

The symbol is "Ai" meaning love, and "Ga Ai Ra" meaning "Narcissist Demon Who Loves Only Himself."
Pronounced, "Gaara."  

[NarucardX]

It can also be said that combining his name and tattoo means "I love death", or "to love death"...
