Top Definition
a special kind of laugh that some males have,a laugh that causes him to become 'engorged'. This laugh is usually triggered by a conversation or event which makes him feel superior to others. i.e. seeing someone fall, or catching a stupid mistake someone made.

Boner laughs are often present in males who have a superiority complex or lower social skills.

Apart from the obvious 'Tent pitching' some tell tale signs of a boner laugh include
*tilting the head back
*a deep gutteral laugh
(the louder the laugh the stiffer he is)
"Oh My GOD he crashed the server!" HAAAA HAAA HAAAAAA *boing

--later

"Hey did you here his Boner Laugh?"
