Top Definition
Adjective. A small but detectable laughter-like sound produced often enough by a blackberrier while using blackberry's instant messaging service.

Although similar in anoyance levels to a blackberry buzz, this human emmited sound has unparalleled capabilities to produce different types of anger or envy reactions in surrounding human beings.

Studies have shown non-blackberry users are more prone to this type of reactions. Rare but reappearing cases of paranoia and panic attacks have been reported over the years.
Would you please stop it with the blackberry giggles? I am sick and tired of hearing you laugh on some topic i'm unaware of. Are you laughing at me?
