Literally meaning the one who masturbates; and has become dumb because of that, but commonly used instead of a friends name(1). It can also lead to a broken nose if used to address a person one is not familiar with and can be used to threaten as well.

Deriving from the word malakia (to jerk off) it is mainly used in other contexts such as, addressing a friend. In Greece it is the vague equivallent of the word "nigger" between afro-americans, in that it can be used freely among friends but never from an outsider.

From Wikipedia, the free encyclopedia
Malakas (Greek: nom. is a slang word, roughly equivalent to wanker, although it is usually employed where English would use asshole or jerk.1 It derives from the Greek word malakos (or 'malthakos'), which means "soft" or "spoilt, well-used to luxuries of life".2
Usage
In modern Greek, the word malakas is used metaphorically in everyday speech to define the individual that uses no common sense, who instead repeats the same mistakes many times over, while maintaining an attitude of self-righteousness. The relation is probably derived by the common notion according to which excessive masturbation harms the brain. While various swear words wax and wane in popularity, malakas is quite unaffected by phenomena such as this, being characterised by a certain timelesness. In addition, in parts of the world outside Greece, with significant Greek population (e.g. the States), the word malakas appears well known among non-Greek people too. This is perhaps an example of significant cultural exchange.
It falls into the class of slang where it is appropriate to use amongst friends, but may be considered an insult when used against strangers or enemies.
Malakas (female:mala'ko, or also can also be used in a variety of ways in modern Greek, according to the circumstance and the way the word is stressed:
