brown stosh
Can only be done by lads too tough to be worried about retribution. Involved sticking your finger up your arse asking someone naive to "smell my finger" then wiping a brown stosh across their top lip.

This, in later life, can be used to return a pint of beer you don't want. Simply put your finger up your arse, hold the beer up to the barman's nose, being sure to keep your finger on his side of the pint glass. Even if you don't get a free pint, you can say "you just smelled my poo" to the barman. Also known as brown hitler, or shit lip

Is also known as a Dirty Sanchez. An alternative is to run the finger all round the mouth giving a poo goatee rather than just a poo tash. This is known as a Dirty Beppe, and is considerably more difficult to apply.
