When you try talking to a friend who seemingly ignores you for days at a time and gives no attention back, and overall acts like they don't want to be your friend anymore. Just like giving water to a dead plant, the plant will never grow again or give anything back. Hence the name, watering a dead plant.
girl 1: damn, I was talking to Emily last night and it feels like I'm watering a dead plant
girl 2: ditch him, you shouldn't be friends with someone who doesn't match your energy
St. Totteringham's Day is the day celebrated by ArsenalF.C. fans when Tottenham Hotspur can no longer finish above Arsenal F.C. in the English Football League by virtue of not being able to catch their rivals, even if they win every remaining game.
Due to its very nature, St Totteringham's Day is moveable and can occur at varying times during the season based on the respective fortunes of Tottenham Hotspur and Arsenal F.C..
In 2007 it is anticipated that St. Totteringham's Day will fall on Saturday 21st April when Arsenal F.C. travel to White Hart Lane; home of the Tottenham Hotspurds.
