Maddog bro, I remember using much more non-veg words during my teens.  Ahiley alik sudreko bhanoom-na.  Some relatively decent habits of mine from yesteryears:

1. dharodharma... biddhyanasta... gai-ko masu khaney... kassam.  Last one - kassam -  was taken more seriously than the others.  Gai-ko masu ta paaye po khanu - tyeti bela ko Nepal-ma hai - so that one was a relatively easy swear.

2. guccha kheldaa feri chuttai vocabulary thiyo ni:  soori... something something mabbyaa... etc.  khoi birsechu.

3. uulto chappal/shoes still bothers me.

4. uttar tauko raakhera nasutnu re...

This one turned out to be non-veg.  But when I first said it, I did not know what it really meant:

   kaa... kaa... kaa... mampaakhaa khwassaa...
