yeah i kinda made it ambiguous, my bad. i meant as the 2nd, 3rd players in. it also depends on how many players are remaining. if it's a 5v5 having the last player watch the flank is fine, or having the 4th playing anti flash or watching the smokes, but when it's like 2v2 and your mate decides to hold an arbitrary angle instead of helping you clear the site i'd consider that baiting. it ends up being a gamble - if the site is clear for some reason or if you manage to clear it, him holding an angle can settle the round because you act as bait in that situation and the remaining ct has to clutch with no info on one of the players, however if you die while trying to plant that dude is left in a 1v2 with no info on the 2nd player. i'd opt for both players clearing the site and trying to trade instead.
a classic example of a misplay would be A smoke execute on mirage in lower ranks where 2-3 teammates just sit tetris and let the smokes dissipate instead of clearing the site. another example is say in a 2v2 or 2vX in general your teammate decides to get into post plant before the bomb is planted with no info. often times you either get killed while planting or straight after because they are not covering and then they try to clutch it. i would definitely consider that baiting. the only exception that comes to mind regarding this concept is when the post plant position is extremely strong and then it might be worth it like planting for long on dust2, planting for short on mirage, planting for toilets on overpass etc.
