LBM

LBM is an acronym standing for Littlebigman. Littlebigman is a combination of symbolic words, little representing his phallic size, big denoting the size of his ego and man being a mockery of the lack thereof.
An LBM is a constantly talkative, girl-obsessed teen.
The LBM should be drug out into the street and shot after a very painful lovemaking session with a claymore antipersonnel mine.

<Eric> A study found that radiation from mobile phones appeared to have a dramatic impact not only on numbers of sperm, but also their swimming ability or "motility".
<Eric> In both cases, levels were cut by about 30%. Reductions in sperm count and motility lower the chances of conception. "
