Czech Bath

The act of sitting post-intercourse bathing of the bits on a bidet. It originates from Portuguese and Brazilian jokes relating to the onomatopoeia "tschec tschec tschec" alluding to sounds produced by the washing of private parts on a bidet.
Used in jokes as the working class answer to the upper class sophisticated people who like to boast about their Spa visits and activities/therapies such as Scottish Shower and Turkish Bath.

Posh Lady: "oh we went to the Spa and was amazing, I had a delightfully glorious Turkish Bath... don't you love a relaxing Turkish Bath?"
Cleaning Lady: "no, I am not familiar... I only know the Czech Bath"
Posh Lady: "oh I never heard of Czech Bath, what is it like?"
Cleaning Lady: "well, after my husband bones me I sit on the bidet and I go 'tschec tschec tschec' - that's a Czech Bath"
