half laugh

1. You know when you make that really inappropriate joke in front of adults if you're a teen and vice versa, that they really shouldn't laugh at so they just let out a single "HA!"

2. When you laugh at a joke that isnt that funny to make the person feel good.

(On a busride home)
Teen 1: Damn i have a lot of homework to do

Teen 2: Yeah I can't wait to get home and "study" (drug reference hand gesture)
Middle Aged Bus Driver: HA! (half laugh)

laughing coma

to laugh so much, that you go into a coma.

For example, instead of being hit my a bus and put into a coma, you would be hit by a statement(preferably a funny one) that would put you into a laughing coma. Which will then cause you to laugh...alot.

similar in principal to the after shock of an earthquake- an after laugh is a laugh to any humourus comment which is made after the initial humour of the comment is lost...

Tom- it took Tom five minutes to understand the joke- and gave an after- laugh much to the annoyance of his friends...

reddit laugh

A quiet laugh to yourself because you don't want other people to know you're reading reddit. Or a quiet laugh to one's self when no one else is around. Usually for fear of being mocked.

I was in class and did a little reddit laugh when you were smirking at me through the window.

Laughing Boner

1. Medical phenomenon that occurs when a funny story ends in something sexual, illiciting a laugh and a boner.

2. Medical phenomenon that occurs when you are in a tickle fight with an attractive person.

1: Girl - "So, the bee flew down my blouse and I panicked, so I threw my shirt off, but I forgot I wasn't wearing a bra!"

Boy - "Haha... uh-oh... laughing boner"
