Retard mode 

The mode in which an individual loses all abilities/senses and is completely lost with himself/herself. This may occur when one is so confused that they actually become mentally disabled. Another well known occurance is when one intakes two vape packs consecutively to the face.

Maxtard (Full retard mode) 

Maxtard is a short version of a maximal retard, a retarded retard. Max-tard.

This word is depraved from the saying ''Full retard'' wich was mentioned in the movie ''Tropic Thunder'', where someone made a very stupid movie and a man gave him advice to never go full retard.

In short: Never go full retard..

Man1: ''You went full retard. Never go full retard.''

Guy1: ''Oh my god, did you see John totally act stupid when drunk and get hated by all the girls?''
Guy2: ''Yeah, he's so maxtarded, going full retard is always bad.''
Guy3: ''Maxtard (Full retard mode) is such a lame word, you guys.''
