There are many definitions of the word
sandbagging, for now I'll consolidate some of
the definitions I've found into one WU, however
feel free to write better WUs for particular
definitions, and /msg me so I can remove the
short summary in my WU
The act of placing sandbags. Usually used as
defence or for flood control.
To hit someone with a small bag/sack filled with sand
To treat severely or cruely.
To force or coerce. Sandbagged into doing a job
The act of keeping one's skill level lower
than it should be. Very common in any handicap sport, including Golf, Internet games where people resign to lower their score, and in the world of Go.
This can be used to make winning
easier (eg for profit, in competition play, etc).
Sand bagging is a well known concept in
poker and pool, where one will pretend to play
bad for awhile, then when the stakes are high, win.
Aside from the definition above (in sport), sandbagging can also be the act
of betting weakly on a strong hand rather than betting strongly on a weak one.
(Roughly the opposite of bluffing). The check-raise is one such method.
A player will check on a good hand at the beginning of play in the hopes of
luring other players with weaker hands into the game. Once lured the sandbagger
will then try to coach the players into thinking they have the best hand, and
thusly betting high.
Depending on the game and players, this can be frowned upon. Best to check
before you play.
The act of stating a route is easier than it really is.
Why? A climber may state that
a particular route is (for example) a
grade 22 when it's actually more
like a grade 25. One might do this in order to
encourage someone to do a route they can't yet do,
to put a person down, or make themselves feel better.
Generally this is strictly frowned upon in
the climbing community, however there are cases
where it can be a Good Thingtm. eg
If you are trying to encourage a friend to try for
the next grade of climbing, you might say a route
is within his/her reach, and (hopefully) when they
make it, point out their real success.
As an added note, sandbagging is probably not
solely a climbing term, and many other sports
probably have the same, or similar terms.
If you know of another sport where
the term sandbagging is used, /msg me
A term used to describe the act of avoiding assigned work (such as
sentry duty, ambush, listening post duty, etc. Usually done with the
intension the duty assigner doesn't find out.
liveforever for pointing out the obvious (that I missed).
