A loose player would be someone who calls a $10 preflop at a $0.50/$1 with Ten 2 off suit and then goes all in after pairing either the Ten or the 2, or someone who calls a £3 preflop at a £1/£2 and then calls a £100 all in on a double ended straight draw. The pot odds are just terrible for either of these players. They might get lucky and make a winning draw, but if you play the odds, you will beat these players over time.

Many of the poorest players play at poker sites that are often associated with a casino, horse racing and/or sports betting such as Betfair, William Hill, Victor Chandler and Ladbrokes. They tend to strongly believe in lady luck and often do not have a clue about pot odds.

Several poker rooms offer notes function, to facilitate write-ups on opponents. There are also 3rd party tracking and analysis software available for some poker rooms to map your opponents (using historical hands functions). Both these functions make it easier to play a winning game, by better adjusting your game to specific opponents.
