Where I'm from it's to be added to the end of a phrase or sentence in order to give it romantic implications in IM and texts.
Originating from the MSN eye-brow waggling emoticon which is sometimes has the keyboard shortcut "#"
Person: "He walked her home last night" (neutral sentence)

Person: "He walked her home last night #" (meaning something happened between them)

A written symbol for the term "waffle" meaning one who has homo-sexual tendencies or is prone to homo-sexual actions; Represented through hand gestures by placing two fingers of one hand (as in a peace sign gesture) in one orientation and placing two fingers of the other hand behind the first hand and oriented perpendicular to the first hand, thus forming a visually analogous hash mark with the hands;
"Mike Grinnon used to try and pick up chicks at Lupo's by saying he played basketball, that kid's such a #waffle#."

"Dude, #waffle# rule in full effect"

"#WAFFLE#, #WAFFLE#, #WAFFLE#!" (in a berating chant)

Used to express love. Derives from the symbol for heart, <3 , which was typed incorrectly as <#, and then shortened into just #.

I # Arlene, she makes my world go 'round.

I feel so much # for Arlene right now.
