While the word wanker is a more general and term for expressing disdain for somebody, the
word LAF describes a
person with a tendency to show off or brag in an excessive and embarrassing way.
LAF can also be used as
alternative assignment of feminine behaviour.
"well at first i thought this guy delivers, but in the end he was
just another laf."
"don't be such a LAF, come and
drink with the
boys"
