To barelly scrape by, can be used in any situation. Can be used in the form of "Roached" or "Roaching" Derived from the word Cockroach, (insect) infering that cockroaches never die. Originated with a group of young boys playing "guitar hero", if the meter is blinking red and you are about to fail the song but you hit just enough notes to pass, you are "roaching" As in anything else in life, if you are "just passing" then you are roaching. If refering to past tense, it is pronounced "Roached" as in, "that guy Roached into the finals"
(While playing xbox)- "Dude you got shot like five times how are you alive?" "I dont know how dude, im Roaching"
