The term 'lame shit' is essentially a synonym of 'good'.

Primarily used amongst the mid-to-late-teenage community in Woking, UK and the surrounding areas.

Under the influence of crystal meth or crack/cocaine.

When your ass crack gets all slimy, sweaty and stinky because you didn't wipe good enough.

1. From something good to something bad.

2. From famous, popular, successful, or useful to a has-been.

When you take a piece of shit and put it in someone's ass crack. Then you put your dick on top.

An L is a marijuana joint, created with 2 papers that before rolled, has an L shape to it, but normally the L is on its side with the long side going across instead of going up and down, and the smaller end going up and down, then you put the marijuana (preferably mixed with tobacco) in the L, roll it, then enjoy your L joint.
Contrary to popular believe, it's not technically a blunt, a blunt is a cigar re-rolled with marijuana, or you can just buy an already non-rolled blunt paper, an L is a good stepping stone to a blunt, you can fit 1g-1.5g in an L, whereas a blunt can go 3g-5g.
