[Hina Muqadas]

A [rail] enthusiast who follows a particular type of rail traction (for example Class 37 locomotives) and tries to travel as many miles as possible behind their chosen type of [locomotive] to earn the respect of fellow bashers.
They bash trains (travelling behind a specimen of their chosen locomotive class) for the purpose of their own enjoyment, they often [lean out] of windows to hear the engine noise better and often wave their arms in the air (in a manner which can confuse and send dangerous messages to [railway] staff) to show their appreciation of the engine [hauling] their train.
They are the arch-enemy of many rail staff who are not enthusiasts or bashers themselves as their exploits, can be [time wasting] - one wave bashers specialize in is waving his (they are rarely hers) arm upwards to show that he does not believe the driver is applying enough power to make a suitable noise from the locomotive (despite the fact that it could damage the train if too much power was applied to quickly), this sign, to all rail staff means: APPLY BRAKES, and this sign is often used in an emergency.

[Donald Trump]

In London a Basher refers to a cheap [pay as you go] phone. Generally the two types of people who use them are 1) Criminals who want to minimise the risk of having their phones tapped or [traced], or 2) Legit persons who use one alongside a decent contract phone, maybe because they like to separate their calls/contacts for example [splitting] between business/personal or because theyre worried about losing a phone and dont want to lose a nicer phone, for example if theyre going to a club or if they are in a dangerous line of work.
The term Basher originated from the idea that one can bash the phone around without worrying because 1) The cheap phones typically used are usually [simpler] and more [robust] than more expensive phones so they are less likely to break, and 2) Even if the phone breaks you dont care about it.
