A variation on Blunken (taking a shit whilst receiving a blow job). Whilst a man is getting a blow job and shitting, he lifts her head and stabs her in both eyes with his penis so as she is temporarily or permanently blinded. With reference to David Blunket, the blind MP.
"Half way throu the Blunken I prodded her in both eyes with my cock and gave her a Blunket Blunken"
A young cocky and arrogant person (usually in middle to upper management) who is supremely overconfident in their very limited experience/knowledge and has no doubt that their future success is guaranteed when, in fact, said person is far more likely to fall through their own butt-hole and hang themselves than produce positive results.
a variation on the word wunderkind
Todd, recent college graduate and now officemanager, proved he was a blunderkind of the highest order when he spent a week implementing a no gum chewing policy even though the company was on the verge of financial ruin.
