Internet is not reliable but you are.

The Internet is a good start and it saves time for me and others.

I split my sides laughing.
I p*ssed myself laughing.

 

[Tdol]

I bust a gut laughing.

 

[Raymott]

P*ssed is a swear-word now?
Anyhow, I should now clarify that the term isn't, "I passed/pessed/possed/pussed myself".

I'm aware that p*ss[es/ed] isn't considered a swear word in AusE, but it certainly is in BrE and I'm sure I recall an AmE speaker confirming the same is true in that variant. I thought it best to err on the side of caution and add the asterisk.
