¡Larguémonos!

[Tyrn]

Hi,

¡Larguémonos (de aquí)! means "let's get out of here!", clear enough. It looks like larguemos + nos to me (Present Subjunctive of largar). Is there a rule about dropping s from emos in such a case? It looks quite natural, yet I can't find it.

When suffixing the first-person plural reflexive pronoun to the imperative, the 's' is dropped from the first-person plural ending.
A similar rule exists for the second-person imperative of a pronominal verb, only it is the 'd' that is dropped.
This is explained here (https://spanish.kwiziq.com/revision/grammar/conjugate-in-el-imperativo-with-reflexive-pronouns-affirmative-commands), for example.

levantar (imperativo)

{||}1st Person Plural | 2nd Person Plural
{|}levantemos | levantad

levantarse (imperativo)

{||}1st Person Plural | 2nd Person Plural
{|}levantémonos | levantaos

Vamonos is a common example

I agree that vámonos is commonly used, but this particular verb doesn't adhere to the normal rules (check out this post (http://forums.tomisimo.org/showthread.php?p=30158) for more information).
