A cretin is a person that is stupid and has done something of significant stupidity. However it can be used as a general insult not the strongest of insults but still an under appreciated word
Can be used to describe a stupid action example:
" did you hear Jamie's gone and got chlamydia"
"What an absolute cretin/kretin "
And individual or event which detracts the attention of inferior or less desirable people away from what everyone else is doing. It's the person who hosts another party to take the school idiots away from the everyone else, so everyone can enjoy themselves without being anxious about dimwits turning up
Will: "Are you going to Timmy's party?"
George: "I want to, but what if the idiots turn up"
Will: "Don't worry, Lucy's party is on the same day"
George: "Ahhh Lucy is a total cretin blanket"
A Person that is: brainless, stupid, child-like, and full of pointless information that makes no sense and appeals only to other cretins. They can be found in abundance in every single populated internet forum, where they race to post as many mind-numbing messages as possible in a single session. In addition, they seemingly interbreed with other cretins, ensuring that their cretinous genes continue long after they end up dead meaning the Internet will never be rid of their kind. More's the pity.
Jodie and her friends like to post messages on forums about how cool it is to kick cats down stairs and throw banana skins at hungry tramps. Clearly they are cretins and should be eradicated from existence.
Cretin stomp, is when the dnb dj drops the most filthy stinking double, triple or chop drop that one looses all motor skills and must reboot brain. This is done by throwing hands together at knee height looking like a combination of a missed clap and hug whilst simultaneously stomping the floor a singular time. After this action full cretin mode is activated.
