The most horrible expression I ever see on MN is currently staining my eyes in Active Conversations.
"It boils my piss."
Every time I read this, I can taste the stinking caustic ammonia vapours of boiling urine on my tongue and in the back of my throat.
I can see the saucepan boiling away on my hob, pale yellow, a witches' cauldron.
<vom> <vom> <vom> <vom>
Stop it. Please, please.
