I've seen the internet slang `凸{とつ}待{ま}ち` used for "waiting for incoming
(Skype etc) calls" pretty frequently, but what is the etymology and usage of
the word?

I've read on other sites that it came from the following:

> 突撃{とつげき}待{ま}ち → とつげき待{ま}ち → 凸{とつ}げき待{ま}ち → 凸{とつ}待{ま}ち

But why did "attack" come to mean "incoming calls"? And why did `凸{とつ}`
("convex") come to be used instead of `突{とつ}`?

Also, can it be used in a more generic sense, i.e. "waiting for an
[assault/attack]"?

Etymology and usage of 凸待ち
I figure I may as well try to answer my own question:

  * The [ニコニコ大百科 page for 凸](http://dic.nicovideo.jp/a/%E5%87%B8) says this 凸{とつ} comes from that the reading is the same, so I think it's likely it's just that it's easier to input than 突{とつ}. 

However, I might speculate the popularity of
[お凸{でこ}](http://dic.nicovideo.jp/a/%E3%81%8A%E3%81%A7%E3%81%93) may have added
to the popularity of 凸{とつ}, and apparently misreading 凸{とつ}待{ま}ち as 凸{でこ}待{ま}ち
is a fairly common mistake (before asking this question I thought it was read
that way too).

  * [This page](http://bosesound.blog133.fc2.com/blog-entry-169.html) says the meaning of 凸待ち is "waiting for somebody to 'phone attack' them" ("誰かが電凸するのを待っている状態"), so I think that's probably the origin of this phrase. I think it's likely tongue-in-cheek, as a lot of internet slang is.
