just in case its not clear....since the word used is slangy even in English...
Schlock is an English word of Yiddish origin meaning "something cheap, shoddy, or inferior (perhaps from German Schlag, Yiddish shlak, meaning 'a stroke'; also possibly from German "Schlag"/"Schlagsahne", whipped cream)"
In the field of science, "schlock" refers to shoddy methods or unreliable results. In art, "schlock" is sometimes used as a synonym for kitsch.
