Tumblstalk 

Excessively looking at or stalking someone's Tumblr blog. This can include frequent reblogs of this person's blog posts.

Alyssa seems to Tumblstalk Allicia, as all of her posts are reblogs of Allicia's.

tubestalking 

The act of stalking pretty boys (or girls) on the tube (that's London Underground to you)

It was a very dull commute home from work today: the District line was stopping every five minutes and my MP3 player ran out of power. The journey's only redeeming feature was tubestalking this beautiful tourist from Victoria to Embankment.

Tumblrtalk: typing with erronious spelling and punctuation as to display confusion, anger, or bewilderment

White upper middle class nerdy girls:
"Seriously I would just no. nonononono

i mean he gets points for determination i guess?? ?? ? ???"

Normal people: "Jeez, I hate it when people use tumblrtalk."
