Showing up uninvited 

in internet parlance, meant to convey the appearance of an unwanted or undesirable group of people that you weren't seeking out in the first place.

There was an interesting discussion about how to save up for retirement, but then all these bitcoin bros started showing up uninvited.

Water Sheringham 

The most realistic name for a dolphin. Based on the fact that dolphins are complete and utter cunts who know something that we don't but are clever enough to let us know they know something without actually telling us.

In land terms the only thing as cunty as a dolphin is Teddy Sheringham, ex-Spurs footballer.

Dolphins are the Sheringhams of the water, therefore 'Water Sheringhams'.

Look at that Bottlenosed Water Sheringham herding that unfortunate swimmer out to sea where they will be eaten by sharks.

or

How can we sink that enemy submarine? I know, let's strap a bomb to a Water Sheringham and teach it to explode when they get close enough.

lemon shoveling 

The act of forcing lemons up one’s asshole for the sheer joy of it, and squeezing the lemon cum out in the process, as this makes for great lube.

Person 1: Bro I fell asleep with my vibrator in my ass overnight and it was so nasty in the morning!
Person 2: Honestly you deserve it. You could have just been lemon shoveling - it feels amazing and there’s no way you’ll forget you have lemons in your asshole.

your carla is showing 

Used to let A female know her underwear is showing when bent over or crouching.
Not to be confused with the phrase ” your Alex is showing “

A female bends over to get one of the guys a beer. One of the guys sees a bright pink thong sticking way out of her paints. He then announces to everyone "hey your Carla is showing" She then covers it up and usually slaps the accuser.
