Generally, he,she or it is considered as asset in a team, if in a game. Particularly on Call of Duty 4 It is said, that this creature once killed 578 enemies in a Clan match, this however is unproven and no records have been found.

Or sometimes if a fourm user is to either Troll on many fourmsExample: "Trouting it" "Custarding it"(Please note it is unknown if "Custard Trout" is male or female, it is also unknown if he,she or it is real or a legend.)
