You know when...

[flammableBen]

you accidendtly take a swig from the can you've been using as an ashtray?

Just had a close call. Done it before tough and it's fucking horrible.

Easy to do when you get towards the end of a can. not much difference in weight if you grab the wrong one.

I seem to do it too often  :chunder:
Should get a portable ashtray, a wrist band ashtray thing that shuts so it doesn't spill
