examples below:

1. carrying bog roll, as mentioned by geoff in another thread, there's something inside that makes me think everyone's judging me for needing to shit in the near future or that they've immediately assumed you're turtle-heading it and thus are closely studying how you're walking

2. leaving to go for a pish when someone's giving a speech, nomatter how desperate the need i'll try and hold it in lest they see me leave and think i couldn't bear to listen to another word

now you go...
